Answer:
(8,21)
Step-by-step explanation:
Since both equations equal y, set both equaitions equal to each other
and solve for x
4x-11=x+13 , subtract x from both sides
3x-11=13, add eleven to both sides
3x=24, divide both sides by 3 to get x alone
x=8
Substitute x=8 into either equation to solve for y
y=4(8)-11
y=32-11
y=21
Exterior angle equals sum of interior opposite angles
10x = 7x + 30
3x = 30
x = 10 so the exterior angle = 10 x 10 = 100 degrees
