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°
Answer:
Could you please put the values or a graph?
Step-by-step explanation:
Answer:
The second option - 8/81
Step-by-step explanation:
Y = -4x + b
60 = -4(5) + b
solve b
<span>60=−4(5)+b</span><span>60=−20+b</span><span>60−(−20)=b</span><span><span>80=b</span></span>
