Today – Wednesday, March 6, 2013  Warm Up: Solving missing sides of right triangles or angles of right triangles  Pass back Quizzes/ Test Corrections  Learning Target : Use the angle of elevation or angle of depression to find missing sides of a right triangle  Independent Practice

WARM UP: Consider this warm up to be a formative assessment of how well you have been doing so far. I WILL BE COLLECTING your warm up after we have gone over it as a class. 15 MINUTES TO COMPLETE.

WHAT YOU SHOULD BE EXPECTING FOR NEXT WEEK!

ANGLE OF ELEVATION:

ANGLE OF DEPRESSION:

METHOD TO FIND MISSING SIDES USING SPECIAL TRIANGLES: 1. Determine which special triangle right triangle is shown-one angle will always be given. 2. Determine whether sides of the triangle that is given, is a leg (short or long or equal) or a hypotenuse. 3. Use given information from special triangle to plug into given equations, then solve for missing side.

METHOD TO FIND MISSING SIDES USING TRIGONOMETRY: 1. Find the opposite, adjacent and hypotenuse of your right triangle. 2. Use the trig function that contains the sides of your triangle to set up your equation. 3. Solve for x, then use your calculator to evaluate for the missing side.

In Class Work: Angles of Elevation and Depression WS #1 We will check answers as a class.

Return Quizzes: Anyone who received 20 points or less are REQUIRED TO STAY during AT for test corrections. Anyone who want to do test corrections for half credit returned can do so.

HOMEWORK #7: Angles of Elevation and Depression WS#1 If finished, work on other assignments: HW #1: Pg. 436: 3-29 odd HW #2: Pg. 444: 1-6, 8, 10, 12 HW #3: Pg. 461: 3-18 HW #4: 7.4 Special Triangles WS (Kuta) HW #5: Pg. 470: 18-20, 24-29, 31, 32 Pg. 477: 10-15, 18-27 HW #6: Pg. 485: 3-8, 10-18
