Step-by-step explanation:
Given that the angles A, B, C in a Triangle form an arithmetic sequence where A=23 degrees.
The nth term of an Arithmetic sequence is given by the formula: 
Where:
a=first term
n=number of term
d=common difference
In this case,


The sum of angles in a triangle is 180 degrees. Therefore:
∠A+∠B+∠C=180 degrees

Therefore:
Angle C,

Here's a picture I found on google of what a 45 degree angle looks like.
Answer:
45 degrees - complementary means both angles add up to 90.
