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
