Question

Given 15 cot A = 8 , find sin A and Sec A

Answer 1

15 cot A =8

cot A= 8/15 

cot A = 8/15  = base/height
________________________________________________
Let height be 15x and base be 8x

By Pythagoras Theorem,

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

(225 + 64)x^2  = hypotenuse^2

289x^2 = hypotenuse^2

17x  = hypotenuse
_______________________________________________

Now,

sin A = height/hypotenuse

Sin A = 15/17

AND

sec A = hypotenuse/base

Sec A = 17/8



i hope this will help you
