Step-by-step explanation:

x = 37

Step-by-step explanation:

The angle with a measure of 74 degrees and the angle labeled "2x" are vertical angles

Vertical angles are congruent ( equal to each other )

Hence, 74 = 2x

             ^(note that we just created an equation that we can use to solve for x)

Now we solve for x

74 = 2x

step 1 divide each side by 2

74 / 2= 37

2x / 2 = x

we're left with x = 37

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
