What is the area of the triangle to the nearest tenth of a square centimeter? Use special triangles to help find the exact height. State both the exact height and the area to the nearest tenth. Show all your work.

Not too much to sweat, here
We have a 30-60-90 right triangle
The side opposite the 30 degree angle = (1/2) the hypotenuse = 13 = this is one leg
The side opposite the 60 degree angle = 13√3 = this is the other leg
Area = product of the legs / 2 = (13) (13)√3 / 2 = 169√3 / 2 ≈ 146.4 cm^2
BTW....the "height" is optional....it's either one leg length or the other.....depending upon your favorite orientation !!!!
