For a, each time it is taking away 2 places. 3,400,000, taking away 2 zeros is 34,000. Like they have in the example. So you need to take away 2 places for the first blank. For the second blank you need to move the decimal place 2 places to the left. For b, it's taking away 1 place, so do the same thing but with one place. For the first blank, add a place.

We know that AB is perpendicular to CD. (that was given)
Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.
180+180=360
90*4=360 See the similarities?
7x+6= 90 degrees
Subtract 6 on both sides.
7x=84
Divide both sides by 7.
x=12
"B" is the correct answer.
I hope this helps!
