Answer:
Step-by-step explanation:
The two angles are supplementary, which means they add to 180
2x+3x=180
5x = 180
Divide by 5
5x/5 =180/5
x = 36
180° = 70° + (2x-10°) + (x+30°)
180° - 70° = (2x-10°) + (x+30°)
110° = 3x + 20°
110° - 20° = 3x
90° = 3x
x = 30°
A is 2x - 10°
A = 2(30) - 10
A = 60 - 10
A = 50°
