Question

The angles of a triangle are in the ratio 3:4:5. Find the angles?​

Answer 1

Step-by-step explanation:

Angles are in the ratio of 3:4:5

Let the angles be 3x,4x,5x

∴3x+4x+5x=180.=====Sum of the angles of triangle are 180°

∴12x=180

∴x=15

Hence, the angles are: 45 ∘ ,60 ∘ ,75 ∘

Answer 2

Step-by-step explanation:

Let the angles be x...

Then ratio given

3:4:5

Then,

3x, 4x, 5x

We know sum of Angles are 180 degrees

Then,

3x+4x+5x=180

12x=180

x=180/12

x=15
