Given:

AB = 24cm

BC = 7cm

∠B = 90°

To find:

Sin A = ?

Cos A = ?

Solution :

In right angled ∆ ABC,

According to Pythagoras Theorem,

→ AC² = AB² + BC²

→ AC² = (24)² + (7)²

→ AC² = 576 + 49

→ AC² = 625

Taking Square root on both the sides,

We get,

AC = 25

Now,

Sin A = Opposite side of A / Hypotenuse

= BC / AC

= 7 / 25

Cos A = Adjacent side of A/ Hypotenuse

= AB / AC

= 24 / 25

Answer :

Sin A = 7/25

Cos A = 24/25
