Question

Given 15 cot A = 8, find sin A and sec A.​

Answer 1

here is your answer...

Answer 2

Answer: sin A = 5/√89 , sec A = √89/8

Step-by-step explanation:

given, 15 cot A = 8

           =>  cot A = 8/15    [ since , cot A = adjacent side/opposite side]

              adjacent side = 8

              opposite side = 15

        (hypotenuse)²  =  (opposite side)² + (adjacent side )²

                                    =  (15)² + (8)²

                                    =  225 + 64

        (hypotenuse)²  =  289

        =>   hypotenuse = 17

   sin A =  opposite side/hypotenuse       sec A =  hypotenuse/adjacent side

             =  15/17                                                       =  17/8
