Question

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

What is the m∠ABF?

25

35

27.5

40

Answer 1

where is point F? or did you mean ABG?

Answer 2

Angle ABF = half of angle ABC = 1/2 x 70 = 35
Angle BAF = half of angle BAC = 1/2 x 55 = 27.5
Sum of angles in triangle ABF = 180 = 35 + 27.5 + ABF
ABF = 180 - 35 - 27.5 = ?

Answer 4

An incenter is made up of three Angle Bisectors so each Angle is cut in half so ABG is refrerring to angle B because B is in the middle of the three letters representing points. so your answer is half of angle B which you said is 70 so your answer should be 35 degrees

Answer 5

Oh so point F is not G

Answer 6

But I believe my answer is still correct the degree of angle ABF is 35

Answer 7

Thank you!
