ABCD is a rectangle. The length of is 8 units, and m∠ABD is 67°.

The length of is

units, and m∠CBD is

°.

the required answer is 23°

Step-by-step explanation:

you can apply basic property of rectangle to solve this question.

each angle of a rectangle is 90°

now, ∠ABD + ∠CBD = 90°

or, ∠CBD = 90° - 67° (given ∠ABD = 67°)

= 23°
