Question

∆abc and ∆xyz are shown if ab=3.8 , ac=3√3 bc=6 , xy=7.6 yz=12 and angle a=65° , angle b=70° find value of y​

Answer 1

Step-by-step explanation:

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
