Explain briefly how to subtract mixed numbers with
unlike denominators. Be sure to show your solution as a subtraction equation

What is the area of triangle abc if a = 8, b = 11, and c = 15?

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.

Use circumcenter theorem to solve for the given values
