Question below.

OpenStudy (anonymous):

G is the incenter of Δ ABC. m∠A = 55 m∠B = 70 m∠C = 55

OpenStudy (anonymous):

Which one? I'm having trouble figuring this one out.

OpenStudy (anonymous):

u mean which angle is correct?

OpenStudy (anonymous):

Yes!

OpenStudy (anonymous):

There needs to be more info. You can't get an angle, if it is just given that G is an incenter.

OpenStudy (anonymous):

G is the incenter of Δ ABC. m∠A = 55 m∠B = 70 m∠C = 55 What is the m∠ABF? 25 27.5 35 40

OpenStudy (anonymous):

the incenter is the point of intersection of angle bisectors. So A,B,C are all bisected by the lines. ABF = B/2 = 35
