Question

Solve for b small 2 in A =1/2h(b small 1 +B small2), if A =16,H=4, and B small 1=3 B small 2 =

Answer 1

5

Explanation:

Fill in the values and solve the resulting linear equation.

`A=(1)/(2)h(b_1+b_2)\\\\16=(1)/(2)\cdot 4\cdot(3+b_2) \quad\text{fill in given values}\\\\8=3+b_2 \quad\text{divide by 2}\\\\5=b_2 \quad\text{subtract 3}`
