To solve this problem you must apply the proccedure shown below:
1. You must apply the following trigonometric identity:
$sin \alpha =opposite/hypotenuse
$
$\alpha =45 degrees
$
$opposite=300$
$hypotenuse=D
$
2. When you substitute the values and solve for D, you obtain:
$sin(45)=300/D$
$D=300/sin(45)$
$D=424.3 m$
The answer is: $B. 424.3 m$
