Answer 2

$\sf{Answer}$

Step by step explanation:-

Given:-

Triangle

Sides of triangle are

• 100
• x
• x

To find :-

Value of x

Concept used:-

Sum of angles in a triangle is 180°

Solution:-

So,

100 + x + x = 180°

100 + 2x = 180°

2x = 180°-100°

2x = 80°

x = 40°

So, value of x is 40°

_____________________________________

Verification:

Substuite value of x to get LHS=RHS

We got value of x = 40°

So, We got 3 angles in a triangle Its sum should be equal to 180°

100 + x + x = 180°

100 + 40+40 = 180°

100 + 80 = 180°

180° = 180°

Hence

LHS = RHS
