What is the measure of angle abc? enter your answer in the box

Step-by-step explanation:

In the given graph, we observe that figure ABCD is a parallelogram, where AB and DC are parallel, and AD and BC are parallel.

So, the easier way to find the answer is by find the difference between 180° and 85°, which is 180-85=95.

Another way is to consider all angles, we know that angle A and angle C must be the same, and angle D and angle B are also equal. So, basically all angles would be related as

A+B+C+D=360

85+B+85+D=360

B+D=360-85-85=190

B+B=190

2B=190

B=95.

Therefore the angle ABC is 95°.
