Answer:
first you need to find how long the side of the ab triangle is
so to find it you use the reciprocal Pythagorean theorem c2= a2-b2
so a2 -b2 = 6*6-2*2 = 30
so now we now that the side of the ab traingle is the square root of 30
then to find x you use the reciprocal Pythagorean theorem again and it goes x2= 30-c2
so x2= 30 -1*1 = 29
x = the square root of 29

that should do it
