Question

the angle of a triangle are in ration 1:3:5 then what is the sum of all find the messure of each angle

Answer 1

1 : 3 : 5 = 20° : 60° : 100°

Explanation:

Let the angle of the triangle be x

Given the following data;

1 : 3 : 5 = x : 3x : 5x

We know that the sum of the sides of a triangle is equal to 180 degrees.

x + 3x + 5x = 180

9x = 180

x = 180/9

x = 20°

Now, to find the measure of each angle.

For the first side;

x = 20°

For the second side;

3x = 3*20 = 60°

For the third side;

5x = 5*20 = 100°
