🧠 Range Equals Max Height — Set Up One Equation, Get

Read the question slowly. The angle of projection is unknown. The speed is given but you may not even need it. The key fact: range = max height. So set the two formulas equal and solve for .

and .

When you set them equal,  and  cancel from both sides. You are left with a pure trigonometric equation that gives  directly. The speed  is a distractor — it never enters the answer. This is the habit: in any "" type question, the speed and  can
