i need help with my math homework!!!!!!
geometry

The answer to this question is 23. To solve this, write an equation to solve x, This equation will be 12x + 6 = 78. Subtract 6 from both sides to get 12x = 72. Next, divide both sides by 12 to get x = 6. Now, just plug in x for both angles. 4 times 6 is 24, minus 1 is 23. To check this, make sure the other angle (angle NRP) equals 55. 8 times 6 equals 48, plus 7 equals 55. I hope this helped! Could I possibly get brainliest?
