Question

if cos theta =7/25 ,find sin theta​

Answer 1

Answer:

24/25

Step-by-step explanation:

given;

cos theta = 7/25

and B/H = 7/25

so here, B = 7 and H = 25

By using Pythagoras theorem,

P = √(H²-B²)

= √{(25)²-(7)²}

= √(625-49)

= √576

P = 24

then, sin theta = P/H

= 24/25, ans...

Answer 2

Answer:

1. Using identity:sin square theta plus cos squaretheta =1
