Question

if cot ∅=21/20,then find the value of sin ∅*cos∅​

Answer 1

Answer:

cot= H/P SIN = P/H

H= 21, P= 20, B =under root41

sin = 20/21 cos = under root41 / 21

20/ 21 × underroot41 /21

20 under root 41 / 441

Answer 2

Step-by-step explanation:

cot theta = 21/20

hence tan theta = 20/21

so sin theta / cos theta = 20/21 is the answer
