SOHCAHTOA

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic for remembering the definitions of the sine, cosine, and tangent functions in a right triangle: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.

If the angle of elevation is 26 degrees and the distance from the base is 90 feet, how do you find the height of the object?

Back

Use the formula: Height = Distance × tan(Angle). In this case, Height = 90 × tan(26°).
