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

Answer:
infinite
Step-by-step explanation:




To solve this, the problem is solvable by elimination. So you see how the 5y and -5y cancel out? You basically add those two and you add the -7x and 4x and 10 and -10 leaving you with -3x=0. Dividing by each side gives you x=0. Then, plug 0 in for x in -7x+5y=10. Giving you
-7(0)+5y=10.
0+5y=10
5y=10
Divide by 5 on each side giving you y=2. So your answer is (0,2).
