Answer 1

Given:

∠A = 66°

AB = 5 mi

To find:

The distance from point B to point C.

Solution:

Using trigonometric ratio formula:

`$\tan \theta=\frac{\text { Opposite side of } \theta}{\text { Adjacent side of } \theta}`

`$\tan A =\frac{\text { Opposite side of } A }{\text { Adjacent side of } A}`

`$\tan 66^\circ =(BC)/(AB)`

`$2.25 =(BC)/(5)`

Multiply by 5 on both sides.

`$5* 2.25 =5* (BC)/(5)`

`$11.2 = BC` (nearest tenth)

The distance from point B to point C is 11.2 mi.
