Question

the angles of a triangle are in ratio 3:5:4 . find the measure of each of the angles​

Answer 1

Given,

Let The Angles Be 3x , 5x & 4x

Then,

We have,

3x + 4x +5x = 180 [ sum of angles of triangle]

12x = 180

x = 180 / 12

x = 15

Hence the angles are 45(3x) , 60(4x) & 75(5x) .

Answer 2

$\huge\boxed{Answer}$

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°and 75°
