What is the measure of BDC, given that figure ADCB is a rectangle?

1 Answer

  • We are asked to solve for the angle of BDC in the figure which is rectangle ACBD.

    Since it is a rectangle, each corner has a 90°. Initially, it was given that angle BDA is equal to 50°. Then we can solve for BDC, such as the solution is shown below:

    90° = ∠ BDC + ∠ BDA
    90° = ∠BDC + 50°
    ∠BDC = 90° - 50°
    ∠ BDC = 40°

    The answer is 40°.
