Can anyone help me answer this?

Ok since it’s a 45 45 90 right triangle then both sides equal 5. And to find x you do

A^2 +b^2=c^2
5^2 +5^2= c^2
25+25=c^2
50=c^2
Take the square root of both sides and you get X= 5 square root of 2 or 7.071(rounded)

There are 8,654 left

Idon’t feel like doing the math but you need to do 2.24 divided by 7
