A 45 deg - 45 deg - 90 deg triangle is shown .
Prove that if one side length is s, the others are s and s * sqrt(2)

1. Which shows how to find x?
a. sin 45 deg = s/(x'); x = s
b. sin 45 deg = s/x; x = s * sqrt(2); c. sin 90 deg = 2 * (45) deg , x = s * sqrt(2)
d. since the acute angles are the same, x = s

2. Which shows how to find the length of the hypotenuse , c?
a. sin 45^ = s ; sin c = s
b. sin 45 deg = s/(C'); c = s * sqrt(2)
c. tan 45 deg = c/s; c = s
d. tan 45 deg = s/c; c = s * sqrt(2);
