  1. Tonight’s Homework • Memorize all Trig stuff!!Pg. 367 #9 – 24 all

  2. 6.6 Applying Trig Functions Applications Determine the angle between the x – axis and the line y = -3x + 4. • The terminal side of Ɵ is in QIV and lies on the line y = -1.5x. Find all trig function values of Ɵ and the measures of Ɵ and Ɵ’.

  3. 6.6 Applying Trig Functions Definitions • The angle between the x – axis in the positive direction and a line is called the angle of inclinations of the line. • The terms angle of elevation or angle of depression are used to describe the angle between the line of sight and the horizontal.

  4. 6.6 Applying Trig Functions More Applications!  From the top of a 100-ft building, a man observes a car moving toward him. If the angle of depression of the car changes from 22° to 46° during the period of observation, how far does the car travel? • The angle of elevation of the top of a building from a point 100 ft away from the building on level ground is 65°. Find the height, h, of the building. • Draw a picture • Label knowns • Determine unknown • Solve the triangle
