Answer:
Use the Pythagorean theorem; substitute the measurement of the leg into either a or b, and substitute the value of the hypotenuse into c.
Step-by-step explanation:
Since we have a hypotenuse, we know that this must be a right triangle. This means the Pythagorean theorem can be used to find missing measurements.
The Pythagorean theorem states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse; algebraically,
a²+b² = c².
To find the measure of the unknown leg, we substitute the information we know; the known leg will be either a or b (it does not matter which), and the hypotenuse will be c.
