Question

Triangle ABC a = 4 and m angle C=30 If the area of the triangle is 6 what is the length of side b

Answer 1

6m = b

Explanation:

The area of triangle when angle and sides are given = 1/2* sin angle*ab

Area = 1/2 * sin 30 * 4*b

Area = 6m²

6 = 1/2 * sin 30 * 4*b

(6*2)/(sin 30 * 4)= b

12/(0.5*4) = b

12/2 = b

6m = b
