Answer to Problem 42SPR

  93.5°

Explanation of Solution

Given information:

The signal from a tower follows a ray that has its endpoint on the tower and tangent to earth.Assume the tower is at sea level.

  Geometry, Student Edition, Chapter 13.1, Problem 42SPR , additional homework tip 1

Calculation:

It is given that tower is at sea level and angle formed by tangent is 86.5° .

If two tangents intersect in the exterior of a circle, then the measure of the angle formed is one half the differences of the measures of the intercepted arc.

  Geometry, Student Edition, Chapter 13.1, Problem 42SPR , additional homework tip 2

Now find the value of x ,

  12(360°−x−x)=86.5°360−2x=173−2x=173−360−2x=−187x=93.5°

Hence length of arc is 93.5° .
