find tan 30 degrees and tan 45 degrees using the 45-45-90 triangle therom and

Question

30-60-90 triangle theorm

Answer 1

In an easily accessible part of your notebook
make a sketch of a 30-60-90 triangle, and put in the values
1 opposite the 30°
√3 opposite the 60°
2 opposite the hypotenuse
MEMORIZE THESE VALUES
(the smallest is opposite the smallest angle, etc..)

Do the same for the 45-45-90 using sides
1 - 1 - √2

now tanØ = opposite/adjacent or y/x
tan 30 = 1/√3 , look at your triangle
tan 45 = 1/1 = 1
