How do you find the measurement of 3 unknown angles? - Answers

You can use the Law of Cosines- name the 3 sides side "a", side "b" and side "c". Then name the angle opposite side "a" angle A, call the angle opposite "b" angle B, and the angle opposite "c" angle C. Now... a^2=b^2+c^2- 2bc(cos(A)) solve for cosA and then for angle A, works the same for the other angles b^2=a^2+c^2- 2ac(cosB) c^2=a^2+b^2-2ab (cosC)
