What is the length of AC? Round to the nearest tenth.

Solution:

In the triangle ABC,

tan55° = Opposite side/Adjacent side

Opposite side = BC = 15m

Adjacent side = AC

By substituting the values

tan55° = 15/AC

Now solve for AC

AC = 15/tan55°

AC = 15/1.428

AC = 10.5m

Therefore, the length of AC is 10.5m

What is the length of AC? Round to the nearest tenth.

Summary:

The length of AC is 10.5m
