Answer:
C. 1:1
Step-by-step explanation:
In a 45 45 90 right triangle, the side lengths for the legs are both
x and the length of the hypotenuse is 
X^2-2x -3 =0
a =1 b =-2 and c = -3
x = - (-2) +/- sqrt (-2)^2 - 4(1)(-3)
--------------------------------------
2(1)
x = + 2 +/- sqrt [(4) - 4(-3)]
-------------------------------
2
x = +2 +/- sqrt [4 + 12]
--------------------------
2
x = +2 +/- sqrt[16]
-------------------
2
x = +2 +/- (4)
-------------
2
x = 2 + 4 or 2 -4
------- ------
2 2
x = 6/2 or -2/2
x = 3 or x = -1
Do you need to show your work? the answer is 114.25
Well it would be 200 × 8 which would equal to 1600
