Answer:
105°
Step-by-step explanation:
The Arc DB = 150°,
If an angle goes from the center of the circle it is the same as the arc. If the angle is inscribed in the circle it is half the arc.
In this case A is inscribed in the circle so its value is half the arc,
The arc is 360 - 150 = 210°
Angle A = 210 / 2 = 105°

Answer:
Step-by-step explanation:
Let x represent the rate at which the ticket is sold and let y represent the number of tickets sold at that rate.
When x = 4, y = 800
This means that the income from gate takings at this rate is 4 × 800 = $3200
For each 1 dollar increase in the gate fee,management expects 100 fewer customers to buy tickets. It means that the amount earned would be (x + 1)(y - 100)
For the amount to be $3500, it means that
(x + 1)(800 - 100) = 3500
700(x + 1) = 3500
x + 1 = 3500/700 = 5
Therefore, management should charge $5 per person for gate fee so that it collects 3500 dollars from gate takings.
