How do you find the measure of an angle using the tangent function?

Back

To find the measure of an angle using the tangent function, use the formula: Angle = arctan(Opposite/Adjacent).

Front

What is the relationship between the sides of a right triangle and the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides: a² + b² = c².
