Use the image to answer the question.
A triangle has the vertices labeled upper M upper N upper O. Upper N upper O is labeled m, upper M upper N is labeled o, and upper O upper M is labeled n. Angle upper N measures 62 degrees and angle upper M measures 28 degrees.
Find the measure of angle O .
Based on the image and the labels, we can infer that angle MON is labeled as angle "O".
Since angle M is labeled as angle "o", angle O is the complement of angle o.
Therefore, angle O = 90 degrees - angle o.
Now, we know that angle M measures 28 degrees, so angle o = 28 degrees.
Substituting the value of angle o into the equation, we get:
angle O = 90 degrees - 28 degrees = 62 degrees.
Therefore, the measure of angle O is 62 degrees.
