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
T+J=4 hours
x+2x=4 hours
3x=240 minutes
X=80 minutes
Answer:
x 8/9
