Answer 2

QuesTion

In a right angled triangle, right angled at B, Side AB = 5cm , Side BC = 3cm. Find Side AC.

AnsweR

• AC = √34 cm

Step By Step Explanation

Given

• Right angled triangle ABC
• Right angle at B
• Side AB = 5 cm
• Side BC = 3 cm

To Find

• Side AC

Solution

We know that,

By Pythagoras Theorem,

AC² = AB² + BC²

AC² = (5)² + (3)²

AC² = 25 + 9

AC² = 34

AC = √34

Verification

AC² = AB² + AC²

√34² = 5² + 3²

34 = 25 + 9

34 = 34
