Please take 1 minute, and really read the example solution
under problem #12. All of the other eight problems on the
sheet are solved in exactly the same way:
Multiply each side of the equation by the denominator of
the fraction ... the number under the variable (the letter).
This easy step will get you the answer to each of the
eight problems.
I can't help noticing that the title of the sheet is 'extra PRACTICE' .
If someone handed you the answers, then you would not get the
practice. That would be just like stealing from you, and would be
just plain mean.

8x=184°
x=23
Large angle= 7(22)-15= 146°
