Answer:
Step-by-step explanation:
[tex]A = \frac{1}{2}h(b_{1} + b_{2})[/tex]
First let's multiply both sides by 2 to remove the [tex]\frac{1}{2}[/tex] fraction:
[tex]2A = h(b_{1} + b_{2})[/tex]
Next, let's divide both sides by [tex]h[/tex]:
[tex]\frac{2A}{h} = b_{1} + b_{2}[/tex]
Finally, let's subtract [tex]b_{1}[/tex] from both sides:
[tex]b_{2} = \frac{2A}{h} - b_{1}[/tex]
