Answer:
a is 11
Step-by-step explanation:
4+2(5)+-3 is ll
You should find the slope using (y2 - y1) / (x2 - x1) = m
m = (18 - 0) / (10 - (-1))
m= 18 / 11
Therefore the slope is 18/11
Let the angle be x.
Hence, its complement is 90 - x.
x = 3* (90 - x) - 70 = 270 - 3x - 70 = 200 - 3x
4x = 200
x = 50
Thus, the angle is 50°.
