Answer:
C
Step-by-step explanation:
Hey There!
So if you didn't know in an isosceles trapezoid the non parallel sides are congruent
So given the base lengths and the perimeter we subtract the given length from the perimeter and divide that by 2
40-10=40
30-14=16
16/2=8
so the lengths of the non parallel sides would be 8 cm and 8 cm
The answer to this question is true
