Answer:
no
Step-by-step explanation:
u can cut the trapesoid in half and make it into a rectangle then get ur answer
It’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.
28+2x=90
-28 -28
2x= 62
x=31
Answer:
A. congruent; proportional; similar
Step-by-step explanation:
As soon as you see the scale factor is not 1, you know the figures are similar and dimensions are proportional. None of the transformations we study (translation, rotation, dilation, reflection) changes any angles. They remain congruent.
