Question

in given figure, angle ABC ,AB = 6, AC = 12 ,angle B =90° ,angle C= theta and find the value of theta
​

Answer 1

Step-by-step explanation:

90 °

Given:

In △ABC

AB=63cm

AC=12cm

BC=6cm

Solution:

AC2=144

AB2=108

BC2=36

Since,

AC2=AB2+BC2

∴ By Converse of Pythagoras Theorem,

△ABC is an Right Angle Triangle at B.

∴∠B=90o
