Question

If 6 cot A+ 2 cosec A = cot A + 5 cosec A, then secA is
a) 4/5
b) 2/7
c) 5/3
d) 5/4
​

Answer 1

Answer:

hey 6 cotA + 2 cosec A = cotA + 5cosec A

so, 6*cosA/sinA + 2/sinA = cosA/sinA + 5/sinA

                          = 5 cosA/sinA -3/sinA = 0

                       so, 5cos A-3/sinA =0

                      so , 5 cos A - 3 = 0

                                 cos A = 3/5
