Sum of angles in a triangle=180
70°+60°+(8x+2)°=180°
130°+(8x+2)°=180°
Collect like terms
(8x+2)°=180°-130°
8x+2)°=50°
8x=50-2
8x=48
x=6°
Nearest hundred
63600 - 41600 = 22000
hope this helps

Answer: D) Ray NM</h3>
Ray NP starts at point N as the fixed endpoint and goes off forever in the direction of point P.
The opposite would be to turn 180 degrees and go the other way. So we start at N and instead go off forever toward point M. In either case, the starting point is still the same (point N).
When naming rays, the order is important. Ray NM is different from ray MN. This is because the first letter is the fixed end point (that doesn't go off forever in one direction).
Answer:
Only one solution
Step-by-step explanation:
Given that there is a coordinate plane (say xy)
Two lines are given.
One line crosses the y axis at 3 and has a slope of negative 1.
hence equation of I line is y = -x+3
The other line crosses the y axis at 3 and has a slope of two thirds.
So equation is y = 2x/3 +3
Since the two lines lie in the same plane and are having different slopes, they intersect at one point.
Eliminate y to get
-x+3=2x/3+3
Or x=0
y=3
Hence solutionis (0,3) for the system.
