Answer:

the value of x=10°

Step-by-step 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!!!
