Answer 1

Answer:

please mark as brainlist

Answer 2

Answer:

by Pythagorean Theorem (7,24,25) are Pythagorean triplets

verification:-

AB²+BC²=AC²

24²+7²= AC²

576 + 49= AC²

625 = AC²

AC = √625

AC = 25

Step-by-step explanation:

sin A.cosA = ?

sinA = opp/hyp = 24/25

cosA = adj/ hyp 7/25

sinA.cosA = 24/25 x 7/25

= 168/625
