Question

given 15 cot a=8 find value of sin a and sec a​

Answer 1

Answer:

sin a=15/17

sec a=17/8

Explanation:

cota=8/15(base/height)

therefore by Pythagoras theorem,

(15^2)+(8^2)=(hypotenuse^2)

√225+64=hypotenuse

√289=hypotenuse

17=hypotenuse.

therefore,

sin=height/hypotenuse

sec=hypotenuse/base.
