The distance between 2 cell towers is 42 miles. from the western cell tower, a phone signal is 20 degrees north of east and is 48 miles away, how far is this cell phone from the eastern cell tower?

48miles

Step-by-step explanation:

The illustration of the scenario is represented in the attached photo

A triangle WEP is formed.

x = distance of the cell phone from the eastern cell tower

The angles in the triangle

= 70 degrees + 70 degrees + 40 degrees = 180degrees

It is not a right angle triangle. This means that we cannot use Pythagoras theorem. We would apply the sine rule which is as follows:

a/sinA = b/sinB = c/since

a, b and c are the sides of the triangle and A,B and C are the corresponding opposite angles to the sides.

Applying it in our triangle,

x/sin 70 = 48/sin70

x = 48sin70/sin70

x = 480 miles
