And now its time for..The Lame Joke of the day..What happens when you get a bladderinfection? Urine Trouble. 4. Practice Ifsin .5 then ? If cos .7071 then ? If tan B .3919 then B? 5. Solving a Triangle Solving a triangle means: Find the length of all 3 sides Find the measure of all 3 angles. Angles are noted with CAPITAL letters Sides are noted with small letters 6. Example 1 Solve the triangle shownif A 36 and b = 50 7. Example 2- Practice Solve the triangle shownif A 34.6 and a = 120 8. Solving Trig Word Problems1. Draw a picture2. Label everything: Write in angle measurements and lengths. Assign variables to unknown quantities.3. Use SOH CAH TOA. Use the correct trig function (sin, cos, tan)depending upon the information given. 9. Example 11. What is the angle of elevation of the sun when a tree 15 ft. tall casts a shadow 5.2 ft long? 10. Example 22. How far from the base of a building is thebottom of a 20 ft. ladder that makes an angleof 62 degrees with the ground? 11.
