Question

solve the formula for the specified variable.

( a=\frac{1}{2} hleft(b_{1}+b_{2}
ight) ; b_{1} ) (geometry)

( b_{1}= )

Explanation:

Step1: Multiply both sides by 2

$$2A = h(b_1 + b_2)$$

Step2: Divide both sides by \(h\)

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

Step3: Subtract \(b_2\) from both sides

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

Answer:

\(b_1=\frac{2A}{h}-b_2\)
