To find the measure of the angle at point D, we can use the Triangle Angle Sum Theorem. This theorem states that the sum of the measures of the angles in a triangle is always 180 degrees.
We know that angle G is a right angle, which means it measures 90 degrees. We also know that angle O measures 41 degrees. To find the measure of the angle at point D, we can subtract the sum of angles G and O from 180 degrees:
180 degrees - 90 degrees - 41 degrees = 49 degrees
Therefore, the measure of the angle at point D is 49 degrees.
