The measurement of angles are: 20°, 60° and 100°

Step-by-step explanation:

Let x be the first angle

Then according to the ratio

1:3:5

The angles will be x,3x,5x

We know that the sum of interior angles of a triangle is 180 degrees

So,

[tex]x+3x+5x = 180\\9x = 180[/tex]

Dividing both sides by 9

[tex]\frac{9x}{9} = \frac{180}{9}\\x = 20[/tex]

The angles are:

First angle = x = 20°

Second angle = 3x = 3*20 = 60°

Third angle = 5x = 5*20 = 100°

Hence,

The measurement of angles are: 20°, 60° and 100°
