Question

If sin A = 7/9. Find Cos A * Cot A​

Answer 1

Answer:

32/63

Explanation:

sin = P/H

Sin A=7/9 it means 7 is perpendicular and 9 is the hypotneuse.

Now we will have to find base

by using pythagorean theorem

H^2 = P^2+B^2

9×9 = 7×7 + B^2

81=49+B^2

81 - 49 = 32 =B^2

root 32 = base

Cos = B/H

Cos A = root 32/9

cot = B/P

Cot A = root 32 / 7

now cos A×Cot A = root 32 /9×root 32/7 = 32/63
