Well fractions are set up over 100 so if it's 100% it would equal 100/100 or your answer, 1.

now.. notice the template above
so hmm


on a) D is 2
on b) D is -2
on c) A is 2
on d) A is 1/2
Right triangle has one degree = 45 so it's isosceles right triangle.
let y = hypotenuse of small isosceles right triangle
y^2 = 7^2 + 7^2
y^2 = 49 + 49
y^2 = 98
so
x^2 = 98 + 98
x^2 = 196
x = 98
answer
x = 98
