What is the missing side length?
(Use Pythagorean Theorem)

Answers

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

                                [tex]a^{2} + b^{2} = c^{2} \\[/tex]

Now we can insert values into the equation.

                                      [tex]a = 15\\b = b\\c = 25\\[/tex]

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

                                  [tex]15^{2} + b^{2} = 25^{2}\\[/tex]

After we solve for [tex]b[/tex] we get:

[tex]b^{2} = 400\\b = 20[/tex]

Answer:

b = 20

Step-by-step explanation:

15 + b = 25

(you have to square each one)

15 x 15 = 225

b x b = b

25 x 25 = 625

625 - 225 = 400

[tex]\sqrt{400}[/tex] = 20
