Answer:
x = 18
Step-by-step explanation:
the sum of any exterior angle is equal to the sum of any two interior angles
3x-11 + 5x+14 = 9x-15
8x + 3 = 9x - 15
3 = x - 15
x = 18
The answer is 106 your welcome :-)
You use elimination the get x=5 and then plug it in to get y=0 so the coordinate is (5,0)
Is there a picture of the question?
Yes he is right because 100/20 is 5 and 7 times 5 is 35%
