Finding the Hypotenuse in a Right Triangle

Very Easy Geometry Triangles

Consider a triangle where one angle measures 30 degrees, and the length of the side opposite this angle is 5 units. What is the length of the hypotenuse of this triangle?

You can use the sine function in your calculations. Recall that in a right triangle, the sine of an angle is defined as the ratio of the length of the opposite side to the hypotenuse.

Use the formula:

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