geometry

check ans

10) 5
11) x = 33 y = 38 z = 109

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

There is 240 red cars and there is 400 blue cars because 240/3=80 and 80*5=400
