Question

In a right triangle ABC $\angle$ B = ${90}^{\circ }$

If AB=6 cm, BC=8 cm, find AC(in cm)

• A. 10
• B. 12
• C. 5
• D. 8

Answer 1

Answer: (A)

10

R.E.F image

Given a right triangle

$\angle B={90}^{\circ }$

$AB=6cm$

$BC=8cm$

using Pythagoras theorem,

$(AC{)}^2=(AB{)}^2+(BC{)}^2$

$(AC{)}^2=(6{)}^2+(8{)}^2$

$(AC{)}^2=36+64$

$(AC{)}^2=100$

$AC=10cm$

Hence, Option A is correct
