To find: The measure of the angle with the greatest measure. If the sides of a triangle are 18 inches, 21 inches and 14 inches
Answer to Problem 7CFU
Explanation of Solution
Given information: The sides of a triangle are 18 inches, 21 inches and 14 inches
Calculation:
Solve for the angle of the greatest side length by using law of cosines with the angle isolated.
You determine the angle that is being solved for by subtracting its corresponding side length in the numerator.
Simplify and solve for C
