Answer:
95°
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°.
