Question

I dont know what to do here and my teachers be giving out the hardest problems

Answer 1

Explanation:

`a = (1)/(2) h(b1 + b2)`

`2a = h(b1 + b2)`

`(2a)/(h) = b1 + b2`

`(2a)/(h) - b2= b1`

You just have to transfer the formula into one where b1 is given by the other values.

Answer 2

b1 = A/((1/2)h) - b2
