Bo is trying to find the height of a radio antenna on the roof of a local building. He stands at a horizontal distance of 20 met

ers from the building. The angle of elevation from his eyes to the roof (point A) is 18°, and the angle of elevation from his eyes to the top of the antenna (point B) is 42°. If his eyes are 1.57 meters from the ground, find the height of the antenna (the distance from point A to point B). Round your answer to the nearest meter if necessary.

There are 888 employees on The Game Shop's sales team. Last month, they sold a total of ggg games. One of the sales team members
luda_lava [24]

Answer:

\frac{g}{8}-17 games

Step-by-step explanation:

Employees: 8

Sales last month: g

Average: \frac{totalGames}{Employees}

To find out how many games Chris sold, we have to take the average and subtract 17.

\frac{g}{8}-17

Since there are no more values we can use, this is as simple as we can get it. If we knew how many games they sold last month, we could get an exact answer for Chris using this expression.

Answer:

616 square centimeters

Step-by-step explanation:

Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.

Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.

Multiply 14 squared by 22/7:

(22/7)(14^2)

This gives us (22/7)(196); (4312/7); 616.

Therefore, the area of the circle is approximately 616 square centimeters.
