Answer
x = 12.5
Work Step by Step
When looking at this problem, I first looked at what was given. The problem gives the angle 30, the variable, x, for the side opposite the angle, and how long the hypotenuse is. Given this, using sin would help us solve the problem, this is how I set up the problem
sin(x) is opposite / hypotenuse
sin(30) = $\frac{x}{25}$
x = 25* sin(30)
x = 12.5
