2. SOH.CAH.TOA What does it stand for? Opposite Cos (CoSine) Hypotenuse
Sin (Sine)
Hypotenuse
Adjacent
Tan (Tangent)
Adjacent

3. Ex. Word Problem.
A car is traveling up a 40 ft. mountain. The peak of the mountain and the height of the mountain form a 27 degree angle. What is the height of the mountain? 27
COS( 27*) = X/40
COS (27*
Then, press the enter button on the calculator
After, times your Answer by 40.
X= 35.6 ft.
Hypotenuse
40 ft. X
Adjacent

4. The breakdown.
When solving the equation I began by reading the word problem. Next, I drew out the triangle and labeled the sides and angles that were given. After, I set up the equation which was COS( 27*) = X/40. I plugged the equation into the calculator and pressed enter. After, I multiplied the previous answer by forty to find X. As a result, 35.6 ft. is my answer.
