The Sine Rule You need to input 2 pairs of opposite sides and angles to find one unknown value. Note - when finding sides, we choose to put the sides on top! The Sine Rule sin x Step 1: Match up the twosets of opposite sides/angles. o = sin o The Sine Rule x Step 2: To get the sides byitself, multiply the denominatorto the other side. = 14.7 × sin sin 20 o The Sine Rule [Correct to one decimal place] Step 3: Input into yourcalculator. = cm The Sine Rule sin x Now, without the prompts! o = sin o The Sine Rule x = 9.4 × sin sin 43 o The Sine Rule [Correct to one decimal place] x = cm |
