Triangle RST is an isosceles triangle.

Triangle RST is a scalene triangle.

Triangle RST is a right triangle.

Triangle RST is an equilateral triangle.

Answers

Answer:

RST is an isosceles triangle

Step-by-step explanation:.

Required

Determine what type of triangle, is RST.

First, we need to determine the angles in RST

Angle on a straight line is 180°.

So, if <mTS = 130°

Then,

<STR = 180° - 130°

<STR = 50°

Similarly,

<TSR = 180° - 130°

<TSR = 50°

The sum of angles in a triangle is 180°.

So:

<TSR + <STR + <TRS = 180°

50 + 50 + <TSR = 180°

100 + <TSR = 180°

<TSR = 180° - 100°

<TSR = 80°

Hence, the three angles of the triangle are: 50°, 50° and 80°

When just two angles of a triangle are equal; such triangle is referred to as an isosceles triangle

Hence, option A answers the question.


2 Why is adding 6, 10, and 5 to a number the same as
adding 21 to that number?

Answers

Answer:because 6, 10, and 5 equal 21

Adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.

Given that, adding 6, 10, and 5 to a number the same as adding 21 to that number.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the unknown number be x.

Add 6, 10, and 5 to x, we get x+6+10+5 = x+21

Add 21 to x = x+21

So equation is x+21 = x+21

Therefore, adding 6, 10, and 5 to a number the same as adding 21 to that number, because sum of 6, 10, and 5 is 21.

NEED HELP QUICKLY 25 POINTS CALC MULTIPLE CHOICE

Answers

Answer:

The absolute maximum value of f on [-2, 4] occurs at x = 4.

Step-by-step explanation:

We know that the absolute maximum value of f(x) on this interval will occur at either a critical point or an endpoint. The critical points are any point where f'(x) is either equal to zero or not defined. Since f is a polynomial, f'(x) = 3x^2 - 6x is always defined, but is equal to zero at x = 0 and x = 2. We can check the value of f(x) at each critical point and endpoint:

f(-2) = -8

f(0) = 12

f(2) = 8

f(4) = 28

Therefore, f has an absolute maximum value of 28 on the closed interval [-2, 4], which occurs when x = 4.

Step-by-step explanation:

The missing reasons for the given two column proof are respectively;

Reason 2; Definition of Supplementary angles

Reason 3; Substitution Property of Equality

Reason 4;Subtraction Property of Equality

How to complete the two column proof?

From the two column proof, we are given that;

m∠2 = m∠3

Now, for m∠1 + m∠2 = 180°, we see that m∠1 and m∠2 are on a straight line and we know that angles on a straight line sum up to 180°. Thus, the reason is because they are supplementary angles.

Similarly, m∠3 and m∠4 are on a straight line and as such;

m∠3 + m∠4 = 180°

m∠1 + m∠2 = m∠3 + m∠4. This is true because of substitution property of equality.

Lastly, since m∠2 = m∠3, then it means that they will cancel out in the statement 3 and as such we now have;

m∠1 = m∠4. The reason is subtraction property of equality

What is the sum of the exterior angles of a 54-gon?

Answers

Answer: The sum of the exterior angles of a 54-gon should be 360°.

Step-by-step explanation:

A polygon is a closed figure made up of straight lines like triangle (3-gon) , quadrilateral (4-gon) , square(4-gon), pentagon (5-gon) , octagon(8-gon) etc.

The sum of exterior angles of any polygon with n sides ( or n-gon ) is always 360 degrees.

A 54-gon is a polygon with 54 sides.

Therefore , the sum of the exterior angles of a 54-gon should be 360°.
