Answer:

x= √2

y= 2

Step-by-step explanation:

Side a = 2

Side b = 1.41421 = √2

Side c = 1.41421 = √2

Angle ∠A = 90° = 1.5708 rad = π/2

Angle ∠B = 45° = 0.7854 rad = π/4

Angle ∠C = 45° = 0.7854 rad = π/4

C=45°B=45°A=90°b=1.414a=2c=1.414

Area = 1

Perimeter p = 4.82843

Semiperimeter s = 2.41421
