Question

A tire swing hangs straight down. Then a child gets on, swings forward 50°, and swings back 95°. How many degrees forward must the swing go to return to its starting position?

Answer 1

Let's draw a picture of the problem:

From the picture above, we can see that the difference (x) between the second and third position is

`95-50=x`

which gives

`x=45`

How many degrees forward must the swing go to return to its starting position? ​Answer: 45 degrees forward
