Answer 2

Answer:

if cos = 15 upon 17

then sign equals to identity rule number 1

that is *sin squared theta plus cos square theta equals to 1*

by putting the value of cos theta in the Identity rule

sin²+cos²=1

sin²+(15/17)²=1

sin²=1-(15/17)²

sin²= 1-225/324

sin²=324-225/324

sin²=99/324

sin= ✓99/17
