Each blade is 360/5=72° apart from the next blade, so you would need to rotate the top fan by at least 72° to again line up with the bottom fan.
Answer:79°
Step-by-step explanation:
Given the 124° angle, the other angle formed by that line and the top side of the square must be 56°, as they are supplementary angles (they must add up to 180°). This means that the angle formed by that same line and the bottom side of the square is also 56° since it is a corresponding angle and the top and bottom sides of a square are parallel. The angle that a diagonal of a square forms with the sides of a square is always 45°.
So now we have a triangle (in red in my diagram) with angles of 45°, 56°, and x°. The sum of the angles of a triangle must always equal 180°, so we solve for x:
56 + 45 + x = 180
x = 180 - 56 - 45 = 79
So angle x must be 79°.
There is 60 minutes in a hour so there is 50 people in 20 minutes.
60 divide by 20= 3 20 times 3 equals to a hour so now you woud have to multiply the the people. 50 x 3= 150
In a hour there would be 150 people that ride the ferris wheel
Answer:
It would be helpful to show a diagram. But, since they are similar shapes, the sides will be proportional to each other. Find that proportion and you can find the missing side!
