Answer:
504 in3
Step-by-step explanation:
I did the I-Ready too.
72+28+66+81=297
360-297=63
She would need to score 63 on her last exam.
It’s number 12!!!!! I know it already got answered
So the trapezoid has 2 parallel sides making segments AD and BC transversals
Therefore making angle c and angle b add up to 180
(180-3x) + 3x + 180-9x +9x
180 +12x = 360
180= 12x
x= 15
