On your own paper draw a right triangle.
Label the vertical height as 12 cm and the hypotenuse as 20 cm.
Please solve for the base x to the nearest 3 digit decimal answer.
:
Yes, let b = the length of the base
:
a^2 + b^2 = c^2
12^2 + b^2 = 20^2
144 + b^2 = 400
b^2 = 400 - 144
b^2 = 254
b + sqrt%28256%29
b = 16

If you did this way, you did right
