Jed rode his scooter to school at 12 miles per hour and then jogged back at 6 miles per hour. If the round trip took him 6 hours, how far was it to school?

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.

It is a trinomial with a degree of 2 i believe
