Answer:
170°
Step-by-step explanation:
To convert from radians to degrees
degree measure = radian measure ×
, thus
degree =
× 
Cancel π on numerator/denominator and 18/ 180 by 18
degree measure = = 17 × 10 = 170°
10x + 2y = -2
2y = -10x -2
y = -5x - 1 (slope is -5 and a parallel line will have the same slope)
y = mx + b
slope(m) = -5
12 = -5(0) + b
12 = 0 + b
12 = b
so the parallel line is y = -5x + 12
hope this helps, God bless!
The equation x = 180 - (31 + 40) can be used. Because the angles are in a straight line ad straight line equals 180 degrees
