Question

Find the value of x in the triangle shown below

Answer 1

=72.52°

Explanation:

We use sin rule: sinA/a = sinB/b

Angle 32 faces side 4

Angle x faces side 7.2

So,

sinx/7.2 = sin32/4

Cross multiply

4sinx = 7.2sin32

Divide both sides by 4

We have,

sinx = (7.2sin32)/4

sinx = (7.2 * 0.5299)/4

sinx = 3.8153/4

sinx = 0.9538

x = sin⁻¹(0.9538)

x = 72.52°

Answer 2
