 1. Find the trig ratios for <A and <B.

Sin(T)= Cos(T)= Tan(T)=

Sin(H)= Cos(H)= Tan(H)=

Sin(A)= Cos(A)= Tan(A)=

 Let (-8, 2) be a point on the terminal side of angle M. Write the 3 trig ratios.

Sin(D)= Cos(D)= Tan(D)= D 4 √2 7

 Of the sides given (this includes variables), label them as opposite, adjacent, or hypotenuse in reference to the angle given.  What trig ratio can you make with these two sides?  Set up the ratio.  Solve for your variable.

y

 Of the sides given (this includes variables), label them as opposite, adjacent, or hypotenuse in reference to the acute angle we are solving for.  What trig ratio can you make with these two sides?  Set up the ratio.  Solve for your variable.

 When finding a missing ANGLE we use the INVERSES of our trig functions.  SIN -1  COS -1  TAN -1  They are located ABOVE the Sin, Cos,& Tan button on the calculators

Solve for m<T

 Line of Sight- horizontal line from the starting point  Angle of Elevation- angle formed from the line of sight UP to a point  Angle of Depression- angle formed from the line of sight DOWN to a point

 You are working the night shift at the lighthouse. Suddenly you notice a fire in the distance! If you are 60 m above ground and you are looking at an angle of depression of 18 ˚. Find the distance between you and the fire.

 The world’s tallest unsupported flagpole is a 282- ft-tall steel pole in Surrey, British Columbia. The shortest shadow cast by the pole during the year is 137 ft long. To the nearest degree, what is the angle of elevation of the sun when casting the flagpole’s shortest shadow?
