Question

NEED HELP WITH THIS!

Answer 1

h=2A/(b1+b2)

and

b2=2A/h-b1.

Answer 2

Answer: See below

Explanation:

a.

To solve for h, we want to use algebraic properties to isolate h.

`A=(1)/(2)h(b_1 +b_2)` [multiply both sides by 2]

`2A=h(b_1 +b_2)` [divide both sides by b₁+b₂]

`(2A)/(b_1+b_2) =h`

`h=(2A)/(b_1+b_2)`

b.

To solve for b₂, we first multiply both sides by 2. Then, we divide both sides by h. This leaves us with
`(2A)/(h) =b_1+b_2`. To get b₂, you subtract both sides by b₁.
