If it is a right triangle, 1 angle is 90 degrees, and it says that the other is 30, so the last degree would be 60 degrees. This is a special triangle, called a
30 60 90 triangle. One of the rules is that the shortest leg is opposite to the 30, which is 7 in. in this case. Another rule states that the hypotenuse is 2 times the shortest leg, so 7 inches * 2 = 14 inches. To find the other leg, you can use the Pythagorean Theorem (a^2 + b^2 = c^2) and solve for b. However, there is 1 more rule stating that the long leg is equal to the short leg times √3. In this case, that is approximately 12.124 inches, or 7√3 if you do not simplify. I hope this helps!
