1. Answer:

   15 inches

   Step-by-step explanation:

   The shortcut for finding the side lengths on a 30°-60°-90° triangle is that the long leg is

   the short leg × √3.

   So for your question:

   5√3 × √3

   = 5 × √3 × √3

   = 5 × 3

   = 15

   Just in case it comes up next, the other shortcut is that the hypotenuse is double the short leg. Hypotenuse =

   2 × 5√3 = 10√3
