In each problem, angle C is a right angle. Find the side indicated to the nearest tenth and show all work. Find a if b=16, measure angle A=42°

Question

Answer Choices:

A)14.4

B)11.7

C)13

D)14.7

Answer 1

Use definition of Tangent.....tan x = opposite/adjacent.

So tan(42)=a/b.

So solving for a = b*tan42 = 16*tan(42) = 14.4
