Triangle 3060(angles) or 12(sides) This triangle has one 30° angle and a 60° angle, where the opposite side to the 30° angle will be 1k, and the opposite side to the 60° angle will be k√3 and the hypotenuse will be 2k (this means that the hypotenuse will be twice as long as the 1k side) Triangle 4545(angles) or 11(sides)90° right triangle is x x√3 2x In this case, x and x√3 are the shorter and longer sides, respectively, while 2x is the hypotenuse Therefore, x√3 = 8√3 cm Square both sides of the equation ⇒ (x√3) 2 = (8√3) 2 ⇒ 3x 2 = 64 * 3 ⇒ x 2 = 64 Find the square of both sides √x 2 = √64 x = 8cm SubstituteWe know immediately that the triangle is a , since the two identified angles sum to 1 ° 180 ° 1 ° = 60 ° The missing angle measures 60 °
