Answer:
[tex]\sqrt{105}[/tex] or approximately 10.25 cm
Step-by-step explanation:
We can use the Pythagorean theorem to solve for the unknown side since this is a right triangle.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
4^2 + AC^2 = 11^2
16+ AC ^2 = 121
AC^2 = 121- 16
AC ^2 =105
Taking the square root of each side
AC = sqrt(105)
or approximately 10.24695077 cm
