Question

angle b and angle d have what relationship? their measures add to 180 degrees. not enough information. they have the same measurement. their measures add to 90 degrees.

Explanation:

Step1: Recall angle - relationship concepts

In a right - angled triangle or when two angles form a right - angle, if the sum of two angles is 90 degrees, they are called complementary angles.

Step2: Analyze the problem

We need to find the relationship between angle b and angle d. Without seeing the full context of the figure, if we assume that they are part of a right - angled situation (for example, if they are non - overlapping angles that together form a 90 - degree angle), their measures add to 90 degrees.

Answer:

Their measures add to 90 degrees.
