Question

Find the lengths of the remaining sides of the triangle. c = 14 a is 60 degrees b is 30 degrees a = b =

Answer 1

• a=7√3
• b=7

Explanation:

Angle C is ...

C = 180° -A -B = 180° -60° -30° = 90°

This is a right triangle with hypotenuse length 14.

a = c·sin(A) = 14·sin(60°) = 7√3

b = c·sin(B) = 14·sin(30°) = 7

The remaining sides are b=7 and a=7√3.
