|x+y| = |-8+(-13)| = |-8-13| = |-21| = 21
(-2^3) = -8.
-2 times 3 = -6.
The expression is now -6 - (-8).
-6 + 8 = 2.
The answer should be 2.
The answer would be 42 degrees because the total of a triangle is 180 degrees. So you would subtract 180 and 42 (180-42) and that gives you 138 and since the two angles that are touching are the same
Answer:
they are vertical angles
