Answer:
7 sqrt(2)/2 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 45 = x/7
7 sin 45 =x
7 sqrt(2)/2 =x
Answer:
![\large \boxed{\mathrm{D. \ \displaystyle \frac{7\sqrt{2} }{2 }}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Cmathrm%7BD.%20%5C%20%5Cdisplaystyle%20%5Cfrac%7B7%5Csqrt%7B2%7D%20%7D%7B2%20%7D%7D%7D)
Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve the problem.
![sin \theta = opp/hyp](https://tex.z-dn.net/?f=sin%20%5Ctheta%20%20%3D%20opp%2Fhyp)
The opposite side to the angle 45 degrees is x and the hypotenuse of the triangle is 7.
![sin 45 = x/7](https://tex.z-dn.net/?f=sin%2045%20%3D%20x%2F7)
Multiply both sides of the equation by 7.
![7 sin 45 = x](https://tex.z-dn.net/?f=7%20sin%2045%20%3D%20x)
Simplify the value.
![\displaystyle \frac{7\sqrt{2} }{2 }=x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B7%5Csqrt%7B2%7D%20%7D%7B2%20%7D%3Dx)
