In Δ ABC, bisectors of ∠ A and ∠ B intersect at point O. If ∠ C = 70° . Find measure of ∠ AOB.
Since we have given that
ABC is a triangle.
Bisectors of ∠A and ∠B intersect at point O.
So, a measure of ∠C = 70°.
So, ∠AOB would be
The measure of ∠AOB is given by
`90^circ + (angle C)/2`
`= 90^circ + 70/2`
`= 90^circ + 35^circ`
Hence, the measure of ∠AOB = 125°.
