<u>Angles in a Right Triangle</u>
When the side lengths of a right triangle are known and an angle must be determined, we can use the trigonometric ratios that relate angles and sides.
The tangent ratio is defined as:
Opposite leg to angle A is 8 and adjacent leg is 7, thus:
Using the inverse tangent funcion:
Calculating:
A = 48.81°
