Question

The three angles in a triangle are in the ratio 1:3:5. Find the angles

Answer 1

30:60:100

Explanation:

angles of triangle =180°

sum of ratios

1+3+5=9

finding for the first one which is one

1/9×180°=20°

finding for the second one which is three

3/9×180°=60°

finding for the third one which is five

5/9×180=100°

adding all the angles

20°+60°+100°=180°

Answer 2

1:3:5

20:60:100

Explanation:

angles in a triangle add up to 180

so we add 1,3 and 5 to get 9

to find out how much 1 part is worth we do 180÷9 to get 20

so 1 part=20

so we we do:

20x1=20

20x3=60

20x5=100
