Two sides of a triangle have measures 3 ft. and 6 ft. Also, these sides form a vertex whose angle measures 60 degrees. Calculate the missing attributes of the triangle. Statements: x² + 3² = 6², where x is the 3rd side of the triangle. x² = 3² +6² + 2⋅3⋅6⋅cos 60°, where x is the 3rd side of the triangle. x² = 3² + 6² − 2⋅3⋅6⋅cos60°, where x is the 3rd side of the triangle. (sin 60°)/3 = (sinθ)/6, where θ is an unknown angle.
