one of the legs of a right triangle measured 12cm and the other leg measures 7cm find the measure of the hypotenuse

Answers

Answer: 14

Step-by-step explanation: The Pythagorean Theorem states that a^2 + b^2 = c^2, where a=leg one, b=leg two, and c=hypotenuse. Using this, our formula will be 12^2 + 7^2. Twelve squared is 144, and seven squared is 49. Added together, the sum is 193. To change this to an unsquared form we must square root it. [tex]\sqrt{193}[/tex]  equals about 13.89. Fourteen if you round up to the nearest whole number.  But just a warning, I don't know what place you are supposed to round to so you may have to use the underlined value instead.

Answer:

Using pythagoras theorem : hypotenuse² = opp² + adj ²

: hyp² = 12² + 7²

hyp² = 193

therefore hypotenuse = root of 193

Answers

Answer:

Yes

Step-by-step explanation:

Linear Equations

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.

What is a Linear Equation?

An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line.

Answers

Answer:

x = -11/3 or 3.666y = -1

Step-by-step explanation:

Given:

1) -3x -5 = 6

2)- 4 ( y - 2 ) =12

To Find:

Value of x for no. 1Value of y for no. 2

Solved:

1)-3x -5 = 6

Transpose -5 from LHS to RHS

=> -3x = 6+5=> -3x = 11

Transpose -3 from LHS to RHS

=> x = (11/-3)=> x = -11/3=> x = -3.666

2) -4(y-2) = 12

Apply distributive property

=>(−4)(y)+(-4)(-2)=12=>-4y+8 = 12

Transpose 8 to RHS

=> -4y = 12-8=> -4y =4

Transpose -4 to RHS

=> y = 4/-4=> y = -1

9. A triangle has sides whose lengths are 5, 12, and 13. A similar triangle could have sides with lengths
of ? Give side lengths of two different similar triangle.

Answers

Answer:

One similar triangle: 15, 36 and 39

Another similar triangle: 10, 24, 26

Step-by-step explanation:

When a triangle is similar, it has corresponding sides that are each longer are shorter than the original triangle by a scale factor.

Scale factor

A scale factor is a number that you multiply the original triangle's sides by. After multiplying each original side, you get the side lengths of a new and similar triangle.

The original sides from the question are 5, 12 and 13.

First similar triangle

Let's pick 3 to be a scale factor.

Multiply every original side by the scale factor to get the side lengths of a similar triangle.

5 × 3 = 15

12 × 3 = 36

13 × 3  = 39

∴ One similar triangle can have the sides 15, 36 and 39.

Second similar triangle

Let's pick another scale factor: 2

Now, we do the same. Multiply the original sides by the scale factor.

5 × 2 = 10

12 × 2 = 24

13 × 2  = 26

∴ Another similar triangle can have the sides 10, 24 and 26.

Choosing a scale factor

We can pick almost any number to be a scale factor. If we pick a scale factor that is:

greater than 1, then the similar triangle will be larger.a fraction, then the similar triangle will be smaller.

We can make an infinite amount of other similar triangles just by changing the scale factor.

Answers

Answer:

Step-by-step explanation:

I have the same question and that was the correct answer

y= x+ 3 is flatter.

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity. If there is no 'equal to' symbol in the statement, it means it is not an equation.

As, the slope of y = x + 3 is 1.

So, the gradient is 1.

So, y = 2x + 3 is flatter

The slope of 2x-1 is 2

and, the slope of y= -4x+3 is -4

and the gradient is -4.

So, y= -4x +3 is steeper.

Answers

Answer:

1) 104

2) 132

3) 110

4) 112

5) 105

Step-by-step explanation:

These questions involve the sum of interior and exterior angles.
for the first 4 questions,

Use the formula: (n-2)*180-(sum of remaining angles)

For example q1, it has 4 angles

So substitute 4 into n

(4-2)*180=360

64+99+93+x=360

x=104°

(Do the same for q2-4)

For q5,

Sum of exterior angles of ANY polygon=360°

Therefore,

88+75+92+x=360

x=105°

Pls double check the answers yourself with a calculator, hope you find it helpful! :)

So basically to find an angle of a polygon you have to use the rule of sum of the interior angles of a polygon which is ‘(n - 2)x180’
- whereas the n stands for the number of sides the shape has
Then find the x angle by subtracting the sun of the other angles so;

1. (4-2)x180=360
360 - 99 - 93 - 64 = 104
2.(5-2)x180=540
540 - 82 - 114 - 90 - 122 = 132
3. 180 - 50 - 20 = 110
4. (6-2)x180=720
720 - 92 - 145 - 136 - 102 - 133 = 112

However the last question is a bit tricky since we have to find the exterior angle but it’s the same because (attached photo)
5. (4-2)x180=369
360 - 88 - 75 - 92 = 105

What is the Length of an Arc?

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

where

θ is the angle, that which arc creates at the centre of the circle in degree.

Given the radius of the circle is 3m, while the angle made by the arc at the centre of the circle is 170°. Therefore,

The length of an arc = 2πr×(θ/360°) = 2π × 3 ×(170/360°) = 2.8334π m

Hence, the length of the arc m∠QPR is 2.8334π m.
