Let's Simplify X to equal 1 by dividing by 100. then we divide 420 by 100 to get 4.2, so y=4.2 when x=1, we then multiply by each by 11.
y = 46.2
x = 11
A and E I think because isosceles is two equal and one different and Right because it has a right/90° angle
7 times 2=14
14 times 2=24
24 times 1=24
