Question

4. Given 15 cot A = 8, find sin A and sec A.​

Answer 1

Step-by-step explanation:

15 cot A= 8

cot A= 8/15

CotA= Base/ perpendicular

so base= 8

perpendicular =15

Hypotenuse = ?

by using pythagoras formula

You will find Hypotenuse.

B²+P² = H²

8²+15²=H²

H²=64+ 225

H= 17

so SinA= p/H

= 15/17

and Sec A= H/B

= 17/8
