Finding the Hypotenuse in a Right Triangle

Hard Geometry And Measurement Trigonometry

In triangle ABC, angle A is a right angle, and angle B measures 30 degrees. The length of the side opposite angle B is 5 units. What is the length of the hypotenuse of triangle ABC?

Use trigonometric ratios to determine the length of the hypotenuse. Recall that for a right triangle, the sine function is defined as:

$$ ext{sine}( heta) =\frac{ ext{opposite}}{ ext{hypotenuse}}$$
