Question

If the angles of a triangle are in the ratio 4:5:9, find the measures of the all

angles.

Answer 1

Answer:

sum of angles in triangle is 180degrees

4x+5x+9x=180degrees

18x=180degrees

x=10degrees

angles in triangle are 4(10)=40degrees

5(10)=50degrees,9(10)=90degrees

Answer 2

Answer:

first angle - 40 , second angle - 50 , and third - 90
