Determine which trig ratio (sin, cos, or tan) includes the given angle, the given side, and the missing side. Round all sides to the nearest tenth and all angles to the nearest degree.ġ7 Example 3: Solution Label the sides as opposite, adjacent and hypotenuse, with respect to the given angle. Solve for the remaining angle.Ģ8.3 cm Check that all angles and sides are solved for by completing the triangle.ġ6 Example 3 Try this on your own first!!!! Solve a Right Triangle, Given One Side Length and One Angle Measure Solve the triangle. Substitute all known values into the equation and solve. b a cĢ8.3 cm adjacent hypotenuse opposite Label the sides as opposite, adjacent and hypotenuse, with respect to the angle that you are solving for. Use Pythagorean Theorem to solve for the missing side. Round all sides to the nearest tenth and all angles to the nearest degree. In a right triangle, one angle is 90 and the sum of the two acute angles is 90.ġ3 Example 2: Solution Solve a Right Triangle, Given Two Side Lengths Solve the triangle. Helpful Hint The sum of the interior angles of any triangle is 180. When asked to solve a triangle, find all missing sides and angles.ġ2 Example 2 Try this on your own first!!!! Solve a Right Triangle, Given Two Side Lengths Solve the triangle. If your missing measurement is an angle, use the inverse function (sin-1, cos-1 or tan-1) to find the angle. If your missing measurement is a side length, algebraically determine. Substitute all known values into the chosen trig ratio equation, including the two known measures and the one unknown measure.ġ1 Information Solve for the unknown value. Determine which trig ratio (sine, cosine, or tangent) includes the two known measures and the one unknown measure.

In order to solve for a missing value when given two values, we Label the sides as opposite, adjacent and hypotenuse. A B C θĩ Information SOH CAH TOA is the word that we use to remember these ratios.ġ0 Information We can use these with right triangles to solve for either a missing angle or a missing side. In relation to A, the sides are labelled as shown.Ĩ Information SOH CAH TOA is the word that we use to remember what to do with right triangles to solve for either a missing angle (when given two sides), or a missing side (when given one angle and one side). Take the square root of both sides.ħ More Information Right ∆ABC is shown below. Substitute known values into the formula, keeping in mind that the hypotenuse (17) must be put into the formula as c. Take the square root of both sides.ĥ Example 1b Try this on your own first!!!!

A B C 5 cm 8 cmĤ Example 1a Solution Determining a Side Determine the length of the missing side in each triangle. When two side lengths of a right triangle are known, we can use the Pythagorean Theorem,, to solve for the length of the missing side.ģ Example 1a Try this on your own first!!!! Determining a Side Determine the length of the missing side in each triangle. Topic 1 Solving Right Triangles Unit 3 Topic 1Ĭ2 a2 b2 a2 + b2 = c2 Information Pythagorean Theorem The sum of the areas of the squares attached to the legs of the triangle equals the area of the square attached to the hypotenuse.
