Q. Use the tangent ratio to find the missing leg of this right triangle. Estimate your answer to two decimal places.
Write Tangent Ratio Formula: Write down the tangent ratio formula, which is tan(θ)=adjacentopposite.
Identify Angle and Sides: Identify the angle θ and the lengths of the sides given in the problem. Let's say the angle θ is 35 degrees, the opposite side is the missing leg we need to find, and the adjacent side is 7cm.
Plug Values into Formula: Plug the values into the tangent ratio formula. So, tan(35∘)=7cmmissing leg.
Calculate Tangent Value: Use a calculator to find the value of tan(35∘). Let's say tan(35∘)≈0.70.
Isolate Missing Leg: Multiply both sides by 7cm to isolate the missing leg. So, missing leg =7cm×tan(35)≈7cm×0.70.
Calculate Missing Leg Length: Calculate the approximate length of the missing leg. Missing leg ≈7cm×0.70≈4.90cm.
