B.) 85
They are alternate interior angles so they are the same degree.
V=lw*h/3
So since its a square l and w are the same
11*11 = 121
h=20
20/3= 6.6666666
V=121*6.6666666
V= 806.66667
Answer:
89
Step-by-step explanation:
To find the area of the rectangle, you do 13 times 8. That gives you 104. Now, for the triangle, you do 1/2 base times height. That is 1/2 of (13 - (4 + 4)) times 6. That equals 1/2 of 5 times 6. So 5 times 3 is 15. 104 - 15 is 89. I hope this helped and please mark me brainliest! Thanks.
