TRIANGLE

A triangle is a three-sided polygon that is sometimes (but not always) referred to as the trigon.

Each triangle has three sides and three angles, with some of the angles being the same.

In the case of a right triangle, the side opposite the right angle is known as the hypotenuse, while the other two sides are known as the legs.

Trilateral Relationship of Triangle

A trilateral is a shape with three sides in geometry. 'Of trilateral figures, an equilateral triangle is one with three equal sides, an isosceles triangle is one with two equal sides, and a scalene triangle is one with three unequal sides.'

Triangle Inequality

The triangle inequality asserts that the sum of the lengths of any two sides of a triangle must be larger than or equal to the length of the remaining side in mathematics.

The condition of the triangle's sides

According to the triangle inequality, the lengths of any two triangle sides must be more than or equal to the length of the third side. Only a degenerate triangle with collinear vertices can have that total equal to the length of the third side.

If and only if the side lengths satisfy the triangle inequality, a triangle with three given positive side lengths exists.

The probability that the jury will make a wrong decision is 0.033

The number of jury that makes the wrong decision can be modeled as a binomial random with parameters n=7 and p=0.2. This jury as a whole will make wrong decision if 4, 5, 6, or 7 make the wrong decision.

Now, denote the events with A, B, C, D for 4, 5, 6, 7 respectively. The probability of this union is the sum of probabilities, so that:

P(Jury Error) = P(A)+P(B)+P(C)+P(D)

A card is drawn randomly from a standard 52-card deck. then the probabilities are a) 1/13 b) 3/13 and c) 10/13

There are four 3's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 3. This means that the probability will be:

p = 4/52

p= 1/13

b.

For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:

4*3 =12

The total possible cards are, still, 52, so, the probability will be

p= 12/52

p=3/13

c.

We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face card its:

p=52/52

p=1

so

p( the card is a face card ) + p( the card is not a face card) =1

but, we know that

p( the card is a face card ) =3/13

so

p( the card is not a face card) =1- 3/13

                                                 = 10/13

Triangle ABD is congruent to triangle DCA.

What is congruency of triangles?

Two figures or objects are congruent in geometry if they have the same shape and size, or if one has the same shape and size as its mirror counterpart. Two triangles are congruent if their respective sides are the same length and their corresponding angles are the same size.

Given, AOC and BOD are the diameters of a circle

Then, In triangles ABD and DCA,

∠BAD = ∠ADC = 90°

BD = CA (diameter)

AD = DA (common)

Thus, by RHS rule the triangles are congruent

Step-by-step explanation:

Let x be the amount of 20% saline solution then the amount of 48% will

8 - x milliliters.

So,

0.20x + 0.48(8 - x) = 0.32* 8

0.20x + 3.84 - 0.48x = 2.56

-0.28x = -1.28

x = -1.28/-0.28

  = 4.57 milliliters.

8 - x = 3.43 milliliters

The theorem that proves that lines d and e are parallel is the: A. converse of the alternate exterior angles theorem.

The alternate exterior angles that are formed on each lines that are cross by the transversal are said to be congruent or equal to each other if both lines they lie on are parallel, based on the alternate exterior angles theorem.

Also, we can prove that if the alternate exterior angles are congruent, then the lines they lie on are parallel lines, using the converse of the alternate exterior angles theorem.

Thus, we are given that angle 2 = angle 6. Angles 2 and 6 lie on lines d and e. Since they are equal to each other, they are congruent angles. Therefore, lines d and e are parallel lines based on the converse of the alternate exterior angles theorem.

Line equation is 5x+2y=10. The point (-6,7). An equation line through the given point and parallel to the given equation is 5x+2y+16=0.

Given that,

Line equation is 5x+2y=10

The point (-6,7)

We have to find an equation line through the given point and parallel to the given equation, in slope-intercept form.

Take equation 5x+2y=10

2y=10-5x

y=(10-5x)/2

y=5-5/2x

The slope of the equation is -5/2

Now, the slope equation formula is

(y-y₁)=m(x-x₁)

Here,

m is -5/2

x₁=-6

y₁=7

We substitute in the formula

(y-7)=-5/2(x-(-6))

(y-7)=-5/2(x+6)

2(y-7)=-5(x+6)

2y-14=-5x-30

5x+2y=-30+14

5x+2y=-16

5x+2y+16=0

Therefore,  an equation line through the given point and parallel to the given equation is 5x+2y+16=0.

Answer:

x=4.6

Step-by-step explanation:

Because we are finding C, first use the distributive property.

33-(2c+4)=2(c+7)+c can turn into:

33-2c+4=2c+14+c

Now, combine like terms.

33+4=37

2c+c=3c

Now you are left with:

37-2c=3c+14

Now, add 2c on both sides.

37=5x+14

Next, subtract 14 on both sides.

37-14=23

23=5x

Finally, divide by 5 on both sides
