Pls help!!! Find the measure of GPS and NPH.
Snowcat [4.5K]

Answer: gps no nph are both 140

Step-by-step explanation:

So we know that around the center is equal to 360. So (15 + 5x) = (4x + 20) to find what x equals you subtract 4x from each side to get 15 + x = 20 now subtract 15 from both sides to get x = 5. Now we know that x = 5 so the 2 angles are 40 degrees each. Now subtract those two angles from 360 and you get 280. Then divide by two and you get 140. So, now we know those two angles are equal to 140.

Good luck with your school work. Sorry it took so long.

y = -4x + 3 this line has slope = -4

parallel lines, slope is the same so slope of new line is also equal -4


passing thru (8, -3)


y = mx + b

b = y - mx

b = -3 - (-4)(8)

b = -3 + 32

b = 29


equation:

y = -4x + 29
