  1. A city map is placed on a coordinate grid. The post office is located at the point P(5, 35), the library is located at the point L (15, 10), and the fire station is located at the point F(9, 25). What is the ratio of the length of PF to the length of LF ? A 2 : 3 B 3 : 2 C 2 : 5 D 3 : 5 Warm up MondayMay 5

  3. Lets take a Quiz

  4. Right triangle word problems Hint: Draw a picture!! A six-meter-long ladder leans against a building. If the ladder makes an angle of 60° with the ground, how far up the wall does the ladder reach? How far from the wall is the base of the ladder? Round your answers to two decimal places, as needed. cos(60°) = b/6 sin(60°) = h/6 b = 3 h=5.196152423 The ladder reaches about 5.20 meters up the wall, and its base is 3 meters from the wall.

  5. A flat 12 foot plank rests with one end on the ground and the other end upon a 4 foot ledge. How far from the base of the ledge is the far end of the plank? What is the grade (i.e., angle of elevation)? Jamie is 5' 8" tall. Find the length of her shadow if the angle of elevation of the sun is 30.2º Some wire connects from a pole to point on the ground at an angle of depression of 80º. On the ground, the wire is 4.5 ft from the pole. (a) How much wire is used? (b) How high up the pole is the wire connected?

  6. You will now get into predetermined groups. Each group will be responsible for 4 problems. You will be teaching these 4 problems to the class tomorrow and YES…it is a grade. You need a picture for each problem, the work to be shown AND a detailed description of why you solved the problem that way. Be ready to answer questions from the class as you are the teacher!
