Question

The angles of a triangle riangle are in the ratios given. 4 : 5 :9

Answer 1

Take the angle as x
So 4x,5x and 9x
As we know the total sum of triangle is 180°
4x+5x+9x = 180°
18x = 180°
X= 180°/18
X = 10

First angle = 4* 10= 40
Second angle = 5*10= 50
Third angle = 9*10= 90

Answer 2

Let the angles be 4x
5x
9x

The sum of angles= 180°
4x+5x+9x= 180°
18x=180°
$x = \frac{180}{18}$
x=10°


The angles =4x=4×10=40°
5x=5×10=50°
9x=9×10=90°
