S = (n-2) x 180 to find the total angles.
5-2*180
3*180

540-86-140-138-59=117
answer:
y = 114° and x = 120°
step-by-step explanation:
part A:
- second inner angle: (180°-87°) = 93°
- third inner angle: (180°-30°) = 150°
- fourth, beside y angle: 360° - 150° - 93° - 51° = 66°
- then y = 180° - 66° = 114°
part B:
- there are 6 sides, so inner angle: (6-2)*180 = 720°
- 160° + 123° + 107° + 90° + x + x = 720°
R= 5
You divide -7 by both sides to 1. Cancel out the -7 2. To simplify the -35. So simplified -35/-7=5
Step-by-step explanation:
y -4x = -1
y = 4x -1
then y = Mx + b
m = 4
b = -1
