Problem 10
You are correct. You divide 360 over the exterior angle measure to get 360/72 = 5

Problem 11
x = 33 is correct as this angle is an alternate interior angle pair with the 33 degree angle up top
y = 38 is correct since y+33+109 = 180 solves to y = 38. In other words: 38+33+109 = 180
z = 109 is correct. The opposite angles of a parallelogram are congruent

Answer:
x=21.
Step-by-step explanation:
First you distribute 3 to the parenthesis. You should get 3x-21=42 at this point. Then you add 21 to 42 to get 63. Here you should be at 3x=63. Divide 63 by 3 to get x=3
Y = 4+3x
2x+1 = y
Rewrite as two systems of equations.
3x - y = -4
2x - y = -1
Now use the substitution method to find the point of intersection.
You can also graph both equations on the same xy-plane using your graphing calculator to find the desired point.
