What is the value of x in a right triangle if one leg is 4 and the other leg is unknown?

Back

x can be found using the Pythagorean theorem.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

How do you find the length of a side in a triangle using the sine function?

Back

Using the formula: opposite side = hypotenuse * sin(angle).
