Question

In a right ΔABC, ∠B=90 , if AB = 7 cm, BC = 24 cm find AC.​

Answer 1

Answer:

By Pythagoras Therom:. AC²=AB²+BC²

=7²+24²

AC=√(7²+24²)

=√(49+576)

=√(625)

AC=25 Ans

Answer 2

25 cm

Step-by-step explanation:

GIVEN :-

In a right angled ∆ABC,

• ∠B = 90°
• AB = 7 cm
• BC = 24 cm

TO FIND :-

• The length of AC

__________________________________

SOLUTION :-

The Pythagoras Theorem says,

(hypotenuse)² = (base)² + (perpendicular)²

Because here,

∠B = 90°, so

• AC = hypotenuse
• AB = perpendicular
• BC = Base

So,

AC² = AB² + BC²

=> AC² = 7² + 24²

=> AC² = 49 + 576

=> AC² = 625

=> √AC² = √625

=> AC = √25²

=> AC = 25 cm

Hence,

The length of AC is 25 cm.
