Example 1

Solve triangle ABC if a = 32⁰ , r = 103⁰ and b = 12

Solution

Thus, a = 32⁰ , b = 45⁰ , g = 103⁰ , a = 8.9903, b = 12 and c = 16.5356

\ triangle ABC is solved.

Find the value of 'a' in the adjoining fig.

Solution

In triangle ABC, A + B + C = 180⁰

A = 180⁰- (B + C) = 180⁰ - (22^0> + 110⁰) = 48⁰
