Question

ONE OF THE ANGLES OF A TRIANGLE IS 100° AND THE OTHER TWO ANGLES ARE EQUAL. WHAT IS THE MEASURE OF EACH OF THESE EQUAL ANGLES

Answer 1

Answer:

The other two angles are 40°

Step-by-step explanation:

As we know that sum of a triangle is 180°  

And A.T.Q( According To Question) the other 2 angles are equal

So we will suppose the angles as 'x'

Now sum of a triangle = 180°

so,

100 ° + x + x = 180°

100° + 2x = 180°

2x = 180°- 100°

2x = 80°

x = 80°/ 2

x = 40°

∴ The answer is 40°
