Question

the outer angle of a triangle are in the ratio of 1:3:5 find each angle​

Answer 1

Answer:

Angles are 20,60,100.

Step-by-step explanation:

Ratio of triangle = 1:3:5

Let the angles be = 1x,3x,5x

Sum of the angles of a triangle = 180

1x+3x+5x = 180

9x = 180

x = 180/9

x = 20

So,

1x = 1×20 = 20

3x = 3×20 = 60

5x = 5×20 = 100

So, the angles are 20,60,100.

Answer 2

1x + 3x + 5x = 180

9x = 180

x = 180 / 9

x = 20

As follows,

1x = 1 * 20 = 20

3x = 3 * 20 = 60

5x = 5 * 20 = 100
