Answer:

AC = 2.33

Step-by-step explanation:

take 25 degree as reference angle

using tan rule

tan 25 = opposite/adjacent

0.466 = AC / 5

0.466*5 = AC

2.33 = AC

Answer:  2.33

====================================================

Explanation:

x = length of the unknown horizontal side AC

We have an unknown opposite side and known adjacent side.

Apply the tangent ratio to solve for x

tan(angle) = opposite/adjacent

tan(B) = AC/BC

tan(25) = x/5

5*tan(25) = x

x = 5*tan(25)

x = 2.331538290775

x = 2.33 which is the approximate length of AC
