Answer:
19 degrees
Step-by-step explanation:
Sum of 2 angles is complementary,
x + 71 = 90
x = 90 - 71
x = 19 degrees
The point B has coordinates (-4,2) and C has coordinates (-2,-2). We are going to calculate the slope of the line

Then, we are going to calculate the intercept using the slope m=-2 and the point (-4,2).
y=mx+b
2 = -2*(-4)+b
Isolating b we get
2-8=b= -6
The equation would be
y=-2x-6, option A
Answer:
And find it all urself
