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

Can some one solve this for me
Digiron [165]

Answer:

x = 2

Step-by-step explanation:

24 - 7x = 10

Rearrange terms,

-7x + 24 = 10

Subtract 24 from both sides,

-7x + 24 - 24 = 10 - 24

-7x = 10 - 24

-7x = -14

Divide by sides by -7,

\frac{-7x}{-7}=\frac{-14}{-7}

x=\frac{-14}{-7}

x = 2

Car 1 - 25

Car 2 - 30

(35x30)+(15x25)=1425

30+25=55
