Answer/Step-by-step explanation:
a. Angle y is vertically opposite the angle that measures 80°. Vertically opposite angles are said to be equal to each other, therefore, y = 80°
x + y + 50° = 180° (sum of angles in a ∆)
x + 80° + 50° = 180 (substitution)
x + 130° = 180°
x = 180° - 130° (subtracting 130 from each side)
x = 50°
b. x + 50° = 120° (sum of the 2 opposite interior angles in a ∆ = the exterior angle of the ∆)
x = 120 - 50 (subtracting 50 from each side)
x = 70°
y + x + 50° = 180° (sum of angles in a ∆)
y + 70° + 50 = 180° (substitution)
y + 120° = 180°
y = 180 - 120 (subtracting 120 from each side)
y = 60°

Answer:
3800 tickets sold
Step-by-step explanation:
We know the number of people seated, and we know the percentage of total ticket sales that represents. So, we can find the total number of tickets sold.
seated + not-arrived = total sold
228 + 0.94 × total sold = total sold
228 = 0.06 × total sold . . . . . . . . . . . . subtract 0.94 × total sold
228/0.06 = total sold = 3800
There were 3800 tickets sold for the performance.
T ∝ 1/v
<span>so, t = k/v or tv = k </span>
<span>Then, with t = 2.5 and v = 5 we have: </span>
<span>2.5 = k/5 </span>
<span>so, k = 12.5 </span>
<span>Therefore, t = 12.5/v or vt = 12.5 HOPE IT HELPED</span>
