A bicycle race follows a triangular course.
The three sides of the race are 7km, 24km and 25km.
What is the approximate measure of the angle opposite to side 7 km?
~~~~~~~~~~~~~~~~

Use the cosine rule

    cos(of the angle "a" opposite to side 7 km) =  = 0.96.


    Angle a = arccos(0.96) = 0.2838 radians = 16.26 degrees.    ANSWER

Solved.
