Dana is buying 7 clothing items at a yard sale where all of the clothes are $2.15 each. What is the total of the items Dana is buying?
a. $14.15
b. $14.14
c. $15.05
d. $15.35

7 x 2.15 = 15.05
The answer is C, NOT D

A is correct because 1 and 3 are vertical angles.

B is correct because there are 180 degrees in a triangle. 180-65-55 = 60. Angle 2 is vertical to the third angle, so angle 2 equals 60.

C is incorrect because it is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 ≠ 60.

D is correct because 3 is an exterior angle.  Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 = 120.

In review, A, B, and D are correct.

I hope this helps you =)
