Answer:

\large \boxed{\mathrm{D. \ \displaystyle \frac{7\sqrt{2} }{2 }}}

Step-by-step explanation:

The triangle is a right triangle.

We can use trigonometric functions to solve the problem.

sin \theta  = opp/hyp

The opposite side to the angle 45 degrees is x and the hypotenuse of the triangle is 7.

sin 45 = x/7

Multiply both sides of the equation by 7.

7 sin 45 = x

Simplify the value.

\displaystyle \frac{7\sqrt{2} }{2 }=x
