When you're looking for the changes between the two, it is best to simply look for the differences. In this case, the first equation has a positive 4 included, whereas, the second doesn't. When you've got a positive number, you always subtract it away from the otherside, as you always do the opposite to what the operation is.This is the equation solved.
Hope this helps :)
Triangle on the right is 45 45 90 right triangle
Ratio of leg : hypo = a :a√2
Given hypo = 6 so leg = 3√2
As you know leg of triangle on the right is the hypo of the triangle on the left
Triangle on the left is 30 60 90 right triangle
Ratio of short leg :hypo = a : 2a
You know hypo = 3√2 so leg x = (3√2 ) / 2 = 3√2 / 2
Answer is A. 3√2 / 2
