Answer:

A- 132.59

Step-by-step 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:

Hey there!

We have tan 9= 21/BW

tan 9 (BW)=21

BW= 21/tan 9

BW= 132. 59

Hope this helps :)

C. 6.25 in

Ratios and cross multiplication:
2 inches is to 130 feet as x is to 406.25 feet

2/130 = x/406.25
(2)(406.25) = (130)(x)
812.50 = 130x
Divide both sides by 130
x = 6.25
