Question

find the value of x in this case​

Answer 1

Answer:

value of x is 15

Step-by-step explanation:

We know exterior angle is equal to the sum of two interior angles so here 9x is an exterior angle

9x=6x+3x

Similarly for other 9x as well

6x+3x=9x

So our angles are

6x+3x+3x=180 (Angle sum property of triangle)

12x=180x=180/12

x=15 degrees

So our angles are 6x= 6*15=90

3x= 3*15= 45

3x= 3*15= 45
