How to Use SOHCAHTOA in Problem Solving
Identify the sides (opposite, adjacent, hypotenuse) and angles in the triangle, then apply the appropriate SOHCAHTOA ratio to solve for the unknown value using trigonometric functions․
Step-by-Step Guide to Applying SOHCAHTOA
Identify the sides (opposite, adjacent, hypotenuse) and angles in the right triangle․
Determine which trigonometric function (sine, cosine, tangent) applies based on the known and unknown values․
Set up the equation using the appropriate ratio: sine = opposite/hypotenuse, cosine = adjacent/hypotenuse, tangent = opposite/adjacent․
Plug in the known values and solve for the unknown side or angle․
Use a calculator to find the trigonometric value and round the answer to the nearest tenth if necessary․
Verify the solution by checking if the ratios align with the original triangle measurements;
Example: If the opposite side is 5 and the hypotenuse is 10, use sine = 5/10 = 0․5 to find the angle․
Practicing with worksheets helps master these steps and improves problem-solving accuracy․
Common Mistakes to Avoid When Using SOHCAHTOA
One of the most common errors is confusing the sides (opposite, adjacent, hypotenuse) relative to the angle being measured․
