If the two triangles are similar, then by definition we have that the quotient between two sides of a triangle is equal to the quotient between two sides of the second triangle.
 We have then:
 ((3x) / (4x + 2)) = ((20) / (28))
 Clearing:
 3x = (20/28) * (4x + 2)
 28 * 3x = (20) * (4x + 2)
 84x = 80x + 40
 84x-80x = 40
 4x = 40
 x = (40) / (4)
 x = 10
 answer
 The value of x is 10

<span><u><em>The correct answer is: </em></u>
C 1.556.

<u><em>Explanation:</em></u>
This can be found by locating the csc button on your calculator. Typically it is located as the second option below the sin button as it is the inverse function.
If you cannot locate the csc button on your calculator, you can also use </span>\frac{1}{sin(40)}<span> as csc is its inverse.

Also, it is helpful to note that some calculators have both a degrees and a radians mode for trigonometric functions. You will need to make sure that you are in degrees in order to use a calculator to solve this. </span>
