Explanation:

Answer 2

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
