Answer:

B

Step-by-step explanation:

sine = opposite/hypotenuse

sin45 = x/4

sin45/1 = x/4

cross multiply

1 × x = 4 × sin45

x = 4sin45

x = 2.828427125

x = 2 × square root of 2 = 2.828427125

Answer:

B )  2[tex]\sqrt{2}[/tex]

Steps:

α = 90°, β = 45°, a = 4: b = 2.82842. . .

β = 45°

a = 4

α = 90°

b =  [tex]\frac{4sin(45)}{sin(90)}[/tex]

b = 2.82842. . .

2[tex]\sqrt{2}[/tex] = 2.82842. . .
