In △ABC, m∠A=50∘, m∠B=60∘, and m∠C=70∘. If △ABC is rotated 90∘ counterclockwise to △XYZ, what is the measure of angle Z?

Given:

In and .

is rotated counterclockwise to .

To find:

The measure of angle Z.

Solution:

We know that the rotation is a rigid transformation. It means the image and figure are congruent to each other.

is rotated counterclockwise to . So, .

                     (CPCTC)

Therefore, the measure of angle Z is 70 degrees.

your welcome haha, this is the best place to find answers

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
