Question

Can anybody help me with this equation?? :/

Answer 1

Answer:

72

Step-by-step explanation:

A full rotation takes 360°. From the picture, it would take 5 rotations to achieve such full degree rotation. Hence, each bit of rotation covers 360°÷5=72°

Answer 2

is the object moving? There’s no way for us to know how much it rotates if we don’t see where it was and where it ends up. But I can help you find the answer.

Basically what you need to do is look at how much the object rotates. You want to look at the squares or the pentagon to see how much the object is rotating.

360 degrees is one full spin, we know what that looks like. If the object rotated 360 degrees then all the points on the hexagon end up where they began (same with squares). But I’m guessing it doesn’t do a full spin since all the answers are leas than 360 degrees.

What if the spin is smaller than 360 degrees? Use proportions based on the shapes. For example, every time a point on the pentagon ends up rotating to where the point next to it was, that’s a 360 degrees / 5 = 72 degree change. I calculated that by taking a full spin and dividing it by 5 angles that the pentagon has.

Does that make sense?
