Answer:

x = 5

Explanation:

The given side is opposite the angle, and the unknown is the hypotenuse. The relevant trig relation is ...

Sin = Opposite/Hypotenuse

sin(30°) = (5/2)/x

x = (5/2)/sin(30°) = (5/2)/(1/2) = 5/1

x = 5

Additional comment

In this 30°-60°-90° "special" right triangle, the long leg is √3 times the short leg, so ...

y = (5/2)√3
