Answer:

Step-by-step explanation:
The rectangle has been split into two right triangles. The hypotenuse of the triangle (the diagonal) is 18. The angle in the triangle is 30. All right triangles have unique relationships between their sides depending on the angles. This triangle must be a 30 - 60 - 90 triangle and its sides will be a scaled version of
.
The side 2 correspond to the hypotenuse of length 18. 2*9 = 18 and so the scale factor is 9. To find the remaining sides, multiply each side length by 9 from
.
It becomes
. So the rectangle is 9 by
.
The perimeter of the rectangle is 
Explanation:
Remember: we have to isolate the variable x, so that means we have to get x by itself.
Step 1:
Let’s look at our equation:

Let’s subtract 2x from both sides of the equation, since our goal is to isolate the variable. You could also subtract 6x from both sides, but you would end up with a negative number, and I find it easier to deal with positive numbers.

Step 2:
Now, let’s subtract 57 from both sides of our equation.

Step 3:
Since we have to isolate x, let’s divide both sides of the equation by 4.

Our final answer: x = 64.5
