Question

Find the length of this

Answer 1

A- 132.59

Explanation:

since we have to find the adjacent and already have the opposite we'll use tanθ = opp/adj

tan(9)= 21/WB

WB = 21/tan(9) (make WB the subject)

WB = 132.5887818 or 132.59

Answer 2

Hey there!

We have tan 9= 21/BW

tan 9 (BW)=21

BW= 21/tan 9

BW= 132. 59

Hope this helps :)
