The answer is -7/8\= 7/-8 Thank you!
I need a picture of the figure so I can calculate it.
<span>A=1/2(a+b)h for h.
First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h
You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.
2A = (a + b)h
Now divide both sides by (a+b).
2A/(a+b) = h
Answer:
B
Step-by-step explanation:
they are two 90° .so B is correct I think
