Answer:
Step-by-step explanation:
Given,
⇒cot theta = 7/8
⇒ cot theta = adjacent/opposite
⇒ so, hyp = √113
⇒ [1 + sin theta] [1 - sin theta] /[1 - cos theta] [ 1 + cos theta]
⇒ [1 - sin² theta]/[1-cos² theta] [∵ [a + b] [a - b] = a²+b²]
⇒cos² theta/sin² theta [sin² theta + cos² theta = 1
⇒cot² theta sin² theta = 1 - cos² theta,
⇒ [ 7/8 ]² cos² theta = 1 - sin² theta
⇒49/64
