The measure of ∠DAB equals 125º.

The measure of ∠ACB equals 30º.

What is m∠ABC? Enter your answer in the box.

Triangle A B C with ray A D extended from side A C.

Firstly, we will draw diagram of this problem

we are given

∠DAB=125º

∠ACB=30º

Since, ∠DAB is exterior angle

∠ACB and ∠ABC are interior angles

and we know that

exterior angle is sum of two interior angles

so, we get

∠DAB=∠ACB + ∠ABC

now, we can plug values

125º=30º+∠ABC

∠ABC=95º ... Answer
