A tower has a revolving restaurant 840 feet above the ground. The restaurant makes a complete revolution every 60 minutes. While a visitor was at the tower, the restaurant rotated through 126°. How long was the visitor at the tower? The visitor was at the tower for minutes.

21 minutes

Step-by-step explanation: A complete revolution has 360°. The tower rotates completely after 60 minutes, which means:

360° - 60 min

The restaurant rotated 126° while the visitor was at the tower, so using proportionality rule:

360° - 60 min

126° - t min

t = 21

The visitor was at the tower for 21 minutes.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
