Triangle abc is a right triangle. If side AC equals 5 and side AB equals 10 what is the measure of side BC yes or no?

Yes, you can find the measure of side BC using the Pythagorean theorem. Since triangle ABC is a right triangle and if AC is one leg (5) and AB is the hypotenuse (10), you can calculate BC as follows: ( BC^2 = AB^2 - AC^2 ), which gives ( BC^2 = 10^2 - 5^2 = 100 - 25 = 75 ). Therefore, ( BC = \sqrt{75} ) or approximately 8.66.
