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: 1. x² + 3? = 6?, where x is the 3rd side of the triangle. 2. x² = 3? +6? + 2:3-6-cos 60°, where x is the 3rd side of the triangle. 3. x² = 3? + 6? - 2:3-6-cos60°, where x is the 3rd side of the triangle. 4. (sin 60°)/3 = (sine)/6, where 0 is an unknown angle. None of the other answer choices are correct. O 2 & 4 only O 3 & 4 only O 3 only
