The third set of angles is complementary. Complementary angles are angles that add up to 90°.
56° + 34° = 90°
A. The temperature goes higher-lower-steady/same-lower-same.
B. I do not understand the question
Answer:
(4, 7)
Step-by-step explanation:
The midpoint formula is (((x1 + x2)/2), ((y1+y2)/2)))
x1 +x2 = 1 +7 = 8
8/2 = 4
y1 + y2 = 10 + 4 = 14
14/2 = 7
(4, 7) is the midpoint
Answer:
67.5
Step-by-step explanation:
