Question

If one angle of a triangle is 100' and the other angles are in the ratio of 2:3, find the angles.​

Answer 1

GiVeN :-

• One angle of triangle = 100°

• Ratio of other angles 2:3

To FiNd :-

• Other angles

SoLuTiOn :-

Let the ratio of other angles be 2x:3x

And,

We know that sum of angles in triangle is 180

So,

=> 100 + 2x + 3x = 180

=> 5x = 180 - 100

=> 5x = 80

=> x = 80/5 = 16

Then,

Other angles are

=> 2x = 2×16 = 32°

=> 3x = 3×16 = 48°
