Solve BCD Round the answer to the nearest hundredth

Mathematics
1 answer:

7 0

Answer:

A

Step-by-step explanation:

The measure of angle D can be found using the Interior Angle Sum of a Triangle.

The angles of a triangle add to 180. This means:

90 + 21 + x = 180.

111 + x = 180

x = 69

The solution is A.

Angle B is smaller than Angle D which means CD will be smaller than BC.
