Answer:
The angle x, has the measurement of 40°
Explanation:
Step 1: Define complementary angles
Complementary Angles: Two angles are complementary when the sum of them is equal to 90°. For example, 30° and 60° are complementary because they add up to 90°.
Step 2: Figure out the complementary angle
Since ∠ABD and ∠DBC are complementary, that means that they should add up to 90°. Since the angle value of ∠ABD is 50°, that means that the angle value of ∠DBC should be 90° - 50° = x.
90° - 50° = x
40° = x
Answer: The angle x, has the measurement of 40°
