17) angle 8 = 47 degrees
angle 5 = 47 degrees
angle 3 = 133 degrees
angle 2 = 133 degrees
angle 6 = 133 degrees
angles 4 = 47 degrees
angle 1 = 47 degrees
18) 20 degrees
strategies/steps:
90 - 70 = 20 degrees
b is the vertical angle of the 20 degree angle, so b = 20 degrees
19) 25 degrees
strategies/steps:
b is the vertical angle of the 25 degree angle, so b = 25 degrees
20) x = 43 degrees
strategies/steps:
2x is the corresponding angle of the 86 degree angle, so 2x = 86, and x = 43 degrees
y = 100 degrees
strategies/steps:
y is the alternate exterior angle of the 100 degree angle, so y is 100 degrees
z = 80 degrees
strategies/steps:
z is the supplementary angle of y, and since y is 100 degrees, z must be 80 degrees
