The rule of a geometric sequence:
We have:
Find 
substitute:
If we do not care about order, then a combination is an arrangement of r objects chosen from n distinct objects. It can often be seen written as:
or
Its factorial form is:
Peter reflecting trapezoid ABCD across the y-axis would not change the degree measurement of angle A
The degree measurement of angle A is 115 degrees
<h3>How to determine the degree measurement of angle A?</h3>
From the question, we have:
A = 115 degrees
B = 65 degrees
The transformation is a reflection across the y-axis
Reflection is a rigid transformation; and it does not change the angle measure or side lengths.
After the transformation; we have:
A = 115 degrees
B = 65 degrees
Hence, the degree measurement of angle A is 115 degrees
