Answer:
2x° + 10° = 90°
3x° = 120°
2x° + 5° = 85°
2x° - 15° = 65°
Step-by-step explanation:
360° = 3x° + 2x° + 5° + 2x° + 10° + 2x° - 15°
360° = 3x° + 2x° + 2x° + 2x° + 5° + 10° - 15°
360° = 9x°
9x° = 360°
x° = 360° : 9
x° = 40°
2x° + 10°
= 2(40°) + 10°
= 80° + 10°
= 90°
3x°
= 3(40°)
= 120°
2x° + 5°
= 2(40°) + 5°
= 80° + 5°
= 85°
2x° - 15°
= 2(40°) - 15°
= 80° - 15°
= 65°

Step-by-step explanation:
3x+2x+10+2x+5+2x-15 = 360
9x+15-15=360
9x=360
x=40.
- 3x=3×40=120°
- 2x+5=2×40+5=80+5=85°
- 2x+10=2×40+10=80+10=90°
- 2x-15=2×40-15=80-15=65°.
