Because it's a right angle, you can determine that Angle ABC and Angle CBD=90 degrees. Therefore:

(2x+1)+33=90

2x+1=57

2x=56

x=28

Due to one of the postulates, or whatever (haven't done geometry in 2 yrs, forgive me), angles GJH and FJI are equal to each other. Therefore:

5x+12=6x-10

-x=-22

x=22
