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
let's say that number is "x", so that is then the 100%.
if 150 is 25%, what is "x"?
Answer:
4
Step-by-step explanation:
70 x 4 = 280 but a triangle's area is halved so 140
