Question

sin A =6/10. then cos A =?​

Answer 1

Answer:

Explanation:

GIVEN

sin A=6/10

P/H=6/10

THIS MEANS

PERPENDICULAR=6

HYPOTENUSE=10

WE KNOW THAT IN A RIGHT-ANGLED TRIANGLE

(PERPENDICULAR)²+(BASE)²=(HYPOTENUSE)²

(6)²+(BASE)²=(10)²

36+(BASE)²=100

(BASE)²=100-36

(BASE)²=64

BASE=√64

BASE=8

COS A=B/H

=8/10
