Given:

45°- 45°- 90°

one leg is equal to 2

Work:

The rules for a 45°- 45°- 90° state that both leg are equal to eachother and because of this the hypotenuse is equivalent to x√2. Because of this, we know that the other leg is equivalent to 2, and that since 2 = x, the hypotenuse is 2√2.

Sine = o/h (opposite/hypotenuse)

o = 2

h = 2√2

sinθ = 2/(2√2) --> (2√2)/4 --> √2/2

Tangent = o/a (opposite/adjacent

o = 2

a = 2

tanθ = 2/2 --> 1

Answer:

sinθ = √2/2

tanθ= 1

I hope this helps!
