Special Right Triangles

In a 30-60-90 triangle:

  • The length of the longer leg is times the length of the shorter leg.
  • The length of the hypotenuse is 2 times the length of the shorter leg.


Fing g.

a) miles
b) miles
c) 3 miles
d) 6 miles

Use the length of the shorter leg to find the length of the hypotenuse. Write an equation and solve.

hypotenuse = 2 · shorter leg

g = 2·3 plug in

g = 6 Multiply

So, g = 6 miles.


Find g.
