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.

The measure of the Central Angle indicated is; 45°
<h3>How to find the central angle of a circle?</h3>
The central angle will be the angle subtended at the center by arc FE and arc CB.
Now, we see that angle ∠FOB = 135° and since we know that sum of angles on a straight line is 180°, then we can say that;
Central Angle = 180° - 135° = 45°
Angle subtended by Arc CD at the center is;
θ = 180 - (81 + 45)
θ = 54°
