Answer 1

Answer: See below

Step-by-step explanation:

a.

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

$A=\frac{1}{2}h(b_1 +b_2)$                [multiply both sides by 2]

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

$\frac{2A}{b_1+b_2} =h$

$h=\frac{2A}{b_1+b_2}$

---------------------------------------------------------------------------------------------

b.

To solve for b₂, we first multiply both sides by 2. Then, we divide both sides by h. This leaves us with $\frac{2A}{h} =b_1+b_2$. To get b₂, you subtract both sides by b₁.
