Question

in a right angle triangle ABC Angle B equal to 90degree AB equal to 12cm and BC equal to 10cn find AC​

Answer 1

Step-by-step explanation:

the triangle is a Pythagoras

the Pythagoras theorem is A square plus B square = C square

so,

10square+12square=?

100+144=244

244=15.62 square

answer is 15.62cm

I hope this helps to u

pls mark me the brainist

Answer 2

Answer:

Given

angle B= 90 degree

AB = 12 cm

BC = 10 cm

Using Pythagoras Theoram in ∆ABC

as angle B is 90 degree than side opposite to it will be AC i.e. hypotenuse

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

$ac ^{2} = 12 ^{2} + 10 ^{2}$

$ac ^{2} = 144 + 100$

$ac ^{2} = 244$

$ac = \sqrt{244}$

$ac = 15.62$
