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'
5x-2y = -10
Multiply by 6
= 30x -12y=-60
3x+6y = 66
Multiply by 2
= 6x+12y = 132
So
30x-12y=-60
6x+12y=132
Add those variables
36x= 72
X= 2
