Answer:
the value of x=10°
Explanation:
hey there!
as there is given angles of the triangle i.e. 5x,9x,4x
now adding all of them,
5x +4x+9x=180 (reason: sum of angle of a triangle is 180°)
18x=180
x=180/18
x=10
therefore the value of x is 10
now the value of each angle is;
5x= 5*10=50
4x=4*10=40
9x=9*10=90
hope it helps! thank u!!!
