Question

if cot theta =15/8 then evaluate (2+2sin theta)(1-sin theta)/(1+cos theta)(2-2cos theta)

Answer 1

Answer:

Step-by-step explanation:

cot∅ = 1/tan∅

15/8 = 1/tan

tan=8/15

tan∅= sin∅/cos∅

8/15 = sin∅/cos∅

sin∅=8 , cos∅=15

(2+2sin∅)(1+sin∅)(1+cos∅)(2-2cos∅)

(2+2x8)(1+8)(1+15)(2-2x15)

(2+16)(9)(16)(2-30)

(18)(144)(-28)

-72576
