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

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

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.
