The consecutive angles of a particular trapezoid form an arithmetic sequence. If the largest angle measures \(128\) degrees, what is the measure of the smallest angle?

What is the measure of the smallest angle?

Hello Guest!

The measure of the smallest angle is 180 degrees - 128 degrees = 52 degrees.

The difference is d = (128 - 52) degrees / 3 .

d = 25 degrees 20 angular minutes.
