Question

The angles of a triangle are in the ration 2:3:4. Then the angles are​

Answer 1

Given:

• The angle of triangle in ratio = 2 : 3 : 4

Find:

• Value of each angle

Solution:

• Let's the angles are 2x, 3x and 4x.

➥ So, we know the angle of triangle is 180°.

⟶ 2x + 3x + 4x = 180

⟶ 9x = 180

⟶ x = 20

• Now, we put the value of x in ratios.

⟶ 2 ༝ 20 = 40

⟶ 3 ༝ 20 = 60

⟶ 4 ༝ 20 = 80

• Therefore, the angles of triangle are 40°, 60° and 80°.
