    Im pretty sure, this is a 30 60 90 triangle. so the sides are labled 2a, a, a\[1.)2a\] \[2.) a\] \[3.) a \sqrt{3}\]

    30-60-90 triangle, so: a is shortest side = 9 here 2a is hypothenuse = 18 here a*sqrt(3) is 3rd side = 9√3 here Hint: Do make a good drawing, with the proper angles (30, 60, 90). It helps identifying this is a special triangle!
