Week 3 - Math Finding missing angle using trigonometry steplt-ISOHC.AM Step 1 - Label the sides of the triangle (Hypotenuse, Opposite, Adjacent). This will help find out what type of formula to use (Sine, Cosine, Tangent). Ex: Sine = opposite/hypotenuse, Cosine = Adjacent/ hypotenuse, Tangent = opposite/adjacent. You can remember this as SOH, CAH, TOA. If the triangle has the measurements for opposite and hypotenuse you will be using the sine formula, if it has adjacent and hypotenuse you will be using the Cosine formula, and for the Tangent; you know the drill.

Get “x” by itself by moving your formula to the other side of the equation. But when you move the formula to the other side of the equation it turns into a “inverse formula”. For example: Sin x = opp/hyp -> x = Sin (opp/hyp). So for this example it turn into a “inverse sine” which looks like a negative exponent on top. Example f ✓ Step 2 - Get our equation to look something like this “Sin x = opposite measurement/hypotenuse measurement” depending on the formula you are using. The “x” stands for the angle we are looking for. Step 4 - Solve the equation. For example: x = Sin (opp/hyp). Divide the opposite measurement and the hypotenuse measurement and then multiply with the inverse sine. Then the answer is the angle of the triangle. 80M€ Label __£%%É÷nt → Tanx=¥o step#3_ - -11¥ ✗ = sin Tanx=¥ H" on is ✗ = Tan-11¥ ) → me ) %px=30° p Answer ✗ 30 30 Adj step # 4 Adj 30 Adj
