Take LCM
Then it comes out to be
[sinA (1 + cosA) + sinA (1- cosA)] / (1-cosA)(1 +cosA)
Upon solving it comes out to be
sinA + sinAcosA + sinA -sinAcosA / sin²A
As (1 + cosA)(1-cosA) = 1 - cos²A = sin²A
So overall it comes
2sinA/sin²A = 4
2/sinA = 4
Cross multiply
sinA = 1/2
sinA = sin30°
Angle A or here theta = 30°.
Solve step by step you will get the answer.
