Question

Which function would you use to solve for the length b?

Answer 1

Let's assume

reference angle =B

so,

opposite =b

adjacent=a

now, we can use tan

`tan(B)=(b)/(a)`

now, we can solve for b

Multiply both sides by a

`a*tan(B)=a*(b)/(a)`

`b=a*tan(B)`

so, option-A...............Answer
