Britton rotated trapezoid ABCD 180 degrees on the coordinate pleane. If angle B is 20 degrees and angle D is 90 degrees, what is the degree measurement of angle B'?

Given:

Trapezoid ABCD rotated 180 degrees to get the trapezoid A'B'C'D'.

To find:

The measure of angle B'.

Solution:

We know that, rotation is a rigid transformation. It means the size and shape of the figure remains same after rotation or be can say that image and preimage are congruent.

So, .

                 (CPCTC)

Therefore, the measure of angle B' is 20 degrees.

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 : )

can someone answer this question plz
