Answer 2

Answer:

hello !!

YOUR ANSWER IS → COS A=4/5

Step-by-step explanation:

SIN A = P/H → SIN A = 3/5

MEANS, P = 3 , H = 5 , B = ?

BY PYTHAGORAS theorem

(H)² = (P)² + (B)²

(5)² = (3)² + (B)²

25 = 9 + (B)²

25 - 9 = (B)²

16 = (B)²

√16 = B

4 = B

NOW , H = 5 , P = 3 , B = 4

SINCE , COS A = B/H → COS A = 4/5

HOPE THIS ANSWER IS HELPFUL FOR YOU :-) ;)
