Question

calculate angle d.

Explanation:

Step1: Recall angle - sum property of triangle

The sum of interior angles of a triangle is 180°. In right - triangle DGO, ∠G = 90°, ∠O=41°, and we want to find ∠D.

Step2: Set up the equation

Let ∠D=x. Then x + 90°+41°=180°.

Step3: Solve for x

x=180°-(90° + 41°)=180° - 131° = 49°.

Answer:

49
