To find the measure of the angle at point D in triangle DGO, we can use the fact that the sum of the angles in any triangle is always 180 degrees.
In triangle DGO:
- Angle G is a right angle (90 degrees).
- Angle O is 41 degrees.
Now we can calculate the angle at point D (let's call it Angle D) using the following formula:
Angle D = 180° - Angle G - Angle O
Angle D = 180° - 90° - 41°
Angle D = 180° - 131°
Angle D = 49°
Therefore, the measure of the angle at point D is 49 degrees.
