1 14 x opp adj Tan 24 =x/14x = 614 * tan 24 Work out the trigonometry steps using a flow map:

2 x x Sin x = Cos 27 = x6x X = 74 X = 7 opp adj hyp 2 nd sin(24/25) 6 / cos 27

3 26 x x Tan 26 = Sin x = 16 x X = 33 X = 19 opp adj hyp 16 / tan 26 2 nd sin (10/30)

4 6. A flag pole of height 26 ft has a shadow of length 15 ft at 7am. Find the angle of elevation of the sun according to the diagram. As it gets closer to lunch time, do you think the angle would get smaller or larger? xºxº 26ft 15ft Tanx= nd tan (26/15) 60º

5 60º As it gets closer to lunch time, the sun rises and the shadow gets smaller. It appears the angle gets larger……lets check. 7am 26ft 15ft 26ft 10ft Tanx=26/10 then x=69º 69º 11am

6 7. A plane is making an emergency landing. The runway is 150 yards and he has 200 more yards before he hits land. At what angle will he meet the ground? 200 yds 150 yds x Cosx = ndCos = (150/200) The plane will meet the ground at and angle of 41º hyp adj

7 RECAP What is the sin ratio? oppostie hypotenuse What is the cos ratio? adjacent hypotenuse What is the tan ratio? opposite adjacent What calculator key do you use when calculating the angle? 2 nd If x is on the bottom do you multiply or divide? divide

8 HOMEWORK Page all How many things do you see?
