The bisectors of the angles of the triangle ABC intersect at point O. Find the angle AOB, if the angle B = 60 °, the angle A = 70 °
| November 29, 2020 | education
the bisector divides the angle in half, hence
OAB angle = 60: 2 = 30
OVA angle = 70: 2 = 35
Consider the triangle AOB
the sum of the angles in the triangle is 180, to find the angle AOB, you need to subtract the angles OAB and OBA from 180
180-30-45 = 105
Answer: angle AOB = 105
