Answer:
y = x - 6
Step-by-step explanation:
The slope of y = -x is -1, so the slope of any line perpendicular to y = -x is +1. Thus,
y = mx + b becomes 2 = 1(8) + b, so that b = -6.
The desired equation is y = x - 6.
Check: Does (8,2) lie on this line? Is 2 = 8 - 6 true? YES.
Answer: 41 degrees
Step-by-step explanation:
measure of angles in a triangle is 180 degrees
So
87 + 52 + ? = 180
139 + ? = 180
? = 41
