Answer:
Step-by-step explanation:
- The sum of exterior angles of a polygon is equal to 360 degrees
I believe the answer is 7
Answer:
The order is -(8), -7, -|-2|, |-3|
Step-by-step explanation:
Absolute value makes the number positive. Therefore -8,-7 and then -|-2|, and finally -3 absolute value makes it positive.
First, let's complete the angles in the triangle. Remember that the sum of the angles in a triangle is 180 degrees.
73 + 90 + x = 180
163 + x = 180
x = 17
So, the angle that completes the triangle is 17 degrees. If we look at that angle in the triangle and the one adjacent to it, we can see that those two angles form a linear pair (or are supplementary, both meaning that they add up to 180 degrees).
17 + x = 180
x = 163
So, 17's supplement is 163 degrees. The 163 degree angle corresponds with angle r, and corresponding angles are congruent.
Therefore, angle r is 163 degrees. The correct answer is option C.
