Answer:

10.5 in

Explanation:

Given


tan(55) = (15)/(b)

Required

Find length AC

The question is not detailed enough; so, I'll assume that b represents line AC.

Having said that;

We start by multiplying both sides by b


tan(55) = (15)/(b)


b * tan(55) = (15)/(b) * b


b * tan(55) =15

Divide both sides by tan(55)


(b * tan(55))/(tan(55)) = (15)/(tan(55))


b = (15)/(tan(55))

Find tan(55)


b = (15)/(1.42814800674)


b = 10.5031130731


b = 10.5 (Approximated)

Length AC is 10.5
