1. what is the sum of the exterior angles of a convex polygon?
a. 360. < choice
b. 180(n – 2)
c. 180
d. 360n
2. what is the measure of each exterior angle in a regular 10-sided polygon?
18°
180°
360°
36° < choice
3. if each exterior angle or a regular polygon measures 15°, how many sides does the polygon have?
a. 20
b. 22
c. 24 < choice
d. 26
4. the exterior angles of a triangle measure x°, (2x)°, and (3x)°. what is the value of x?
a. 60< choice
b. 72
c. 30
d. 45
5. the exterior angles of an octagon are 42°, 55°, 39°, 20°, 62°, 45°, and 47°. what is the measure of the eighth exterior angle? show equations and all work that leads to your answer.
360 = 42 + 55 + 39 + 20 + 62 + 45 + 47 + x
360 = 310 + x
360 - 310 = 310 - 310 + x
50 = x
x = 50
