This is a right triangle and to find the length of the missing side you must do pythagorean theorem:


a^(2) +b^(2) = c^(2)

a & b are the legs of a right triangle

c is the hypotenuse. This is the side opposite the right angle

In this case each value is:

a = 5

b = x---------------> This is what you are looking for

c = 12

^^^Plug these number into the pythagorean theorem


5^(2) +x^(2) = 12^(2)

25 +
x^(2) = 144

Isolate x by subtracting 25 to both sides


(25-25) + x^(2) = 144 - 25


x^(2) = 119

The opposite of squaring a number is taking the square root of a number, so to isolate x take the square root of both sides.


\sqrt{x^(2) } } =√(119)

x = 10.9087121146

Then if the question requests it, you can round 10.9087121146

Hope this helped!

Use Pythagorean theory

C^2 = a^+ b^2

In this case you have c and a

B^2= c^2-a^2

B^2 = 12^2-5^2

B^2= 144-25

B^2 = 119

Square root both sides

X= 10.90871
