Hannah wants to find the height of the tallest building in her city.  She stands 107 feet away from the building.  There is a tree 32 feet in front of her that is 18 feet tall.  How tall is the building to the nearest foot?

Draw two triangles ­ set up a proportion ­ show work ­ solve.

Intro to Sine, Cosine, and Tangent

Remember this...

SOH ­ CAH ­ TOA

This is a way to remember the "definitions" of sine, cosine, and tangent.

S : Sine C : Cosine T : Tangent

Care to take a guess what O, A, and H represent?  Hint: it deals with Tuesday's lesson.
