Answer:
Step-by-step explanation:
18/12 = 24/(x-2) Put the similar sides in the propertions.
19/20 in simplest form is 0.95
9/16 in simplest form is 0.5625
Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
