The measure of a central angle is equal to measure of a minor arc. That makes m<GEH=17x+12. By the Vertical Angles Theorem, m<GEH and m<IEF are equal to each other (m<GEH=17x+12=m<IEF). By the same theorem, m<FEG and m<IEH are also equal (m<FEG=8x-7=m<IEH). The angles in a circle must all add up to 360 degrees, 2(17x+12)+2(8x-7)=360. Solve for x, then plug x into the equation for m<IEF.
Hope this helps!
First, you have to convert 1/4 and 1/3 to have the same denominator.
So, 1/4 x 3 = 3/12. 1/3 x 4 = 4/12.
Now, you can add 3/12 + 4/12 = 7/12.
5(3-6x)=4(3x+7)+5x
x= - 13/47

If she has finished 20%, she still has 80% to do. So just calculate .8 times 150.
