8.4 Trigonometry In Right triangles

A. Express sin L, cos L, and tan L as a fraction and as a decimal to the nearest ten thousandth.

Find the value to the ten thousandth.  Sin 15  Tan 67  Cos 89.6

Find the measure of each angle to the nearest tenth of a degree  Cos T =.3482  Tan R =.5555  Sin P =.6103

Find y.

Find the height of the triangle.

 When you need to find the angle measure- set up the problem like normal Then hit the 2 nd button next hit sin, cos or tan (which ever you are using) then type in the fraction as a division problem, hit = Find angle P.

Find angle D.
