Cant believe your teacher never gave you one!

Answer 12

Never seen it ><"
I think 2 is B... I think. I'm insecure in math. I really like this chart, probably going to print it!

Answer 13

For reference, if you have 90 degrees and you want it in pi form. you just divide it by 180. so 90/180= 1/2 and you just multiply the top by pi. so 1 times by pi is pi/2

Answer 14

Thank you :)

Answer 15

wait, one more! i love converting things. to get any radian measures like pi/2 or pi/3 back into degrees you just multiply (pi/2)(180/pi)=90 degrees
So, (pi/3)(180/pi)=60 degrees]
hope that helps! you can always double check your numbers with that chart.
