  2. Problem # 1 • My brother got a 10 ft high charismas tree in his house. The tree has an angle of 50 degreeswith the ground. How far is the foot of the ladder from the wall? ] 10ft TAN(50 ˚)= 10/CA CA= 10/TAN (50 ˚) 10/ 1.19175359259= 5.21ft 50 ˚

  3. Problem # 2 • The distance form the downtown building is 1200 feet high from the American Airline plane. The plane is 20 degrees form the ground. What is the distance form the high school building to the American Airline plane? • Sin (28 ˚) = 1200/x • 1200/ 0.46947156278=2556.06ft

  4. Problem # 3 • A tree is 20 m high. The degree value is 20 degrees. What is the length of QA? Tan (20˚)=20/AQ 20/0.36397023426= 54.94

  5. Problem # 4 • A ladder 5 m long, leaning against a vertical wall makes an angle of 65˚ with the ground. • How high on the wall does the ladder reach? • Sin 65 ˚ = PQ/5 • PQ = sin 65˚ × 5 • 0.90630778703 x 5 = 4.53 m

  6. Problem # 5 • A woodhouse is 150m high. A car is 200m form the woodhouse. The degree value is 45. what is the value form the garage to the woodhouse. • 150m • 200m 45 • Cos (45˚)=200/x • =282.84m
