Question

∆ ABC is right angled at C. AB = 25, and BC = 7 cm, the sin A equals.  (1 Point)
a 7/25
b 7/24
c 24/25
d 25/24​

Answer 1

Answer:

a) 7/25 is the correct ans

Step-by-step explanation:

see your explanation in attached pic

Answer 2

Answer:

C

is correct answer

Step-by-step explanation:

SIN A = perpendicular / hypoteniuse

so by using Pythagoras theorem

H² = B² +P²

(25)² = 7² +P²

625-49 = P²

√576 =P

24=P

SIN A = P/ H

Sin A = 24/25
