Question

In ∆ ABC, right angle at C. AC = 6cm, BC = 8cm
then AB is :​

Answer 1

Answer:

AB = 10cm

Step-by-step explanation:

use Pythagoras theorem

Answer 2

Answer:

10 cm

Step-by-step explanation:

Since the given triangle is a right angle triangle you can find the required side by using pythagoras theorem.

AC = 6cm, BC = 8 cm, AB = ?

By pythagoras theorem,

${ab}^{2} = {ac}^{2} + {bc}^{2}$

$= > {ab}^{2} = {6}^{2} + {8}^{2}$

$= > {ab}^{2} = 36 + 64 \: = 100$

$= > {ab} = \sqrt{100}$

$= > ab = 10cm$
