What is the missing side length?<br> (Use Pythagorean Theorem)
Vedmedyk [2.9K]

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

                                a^{2} + b^{2} = c^{2} \\

Now we can insert values into the equation.

                                      a = 15\\b = b\\c = 25\\

Now we can plug these ☝ values into the Pythagorean Theorem:

                                  15^{2} + b^{2} = 25^{2}\\

After we solve for b we get:

b^{2} = 400\\b = 20
