Angle ADB is a right angle, which is given.
The measure of ADB is 90 degrees by definition of right angle.
The two angles are a linear pair (aka they're supplementary) by definition of linear pair (they're formed by two intersecting lines).
The measure of BDC is 90 because BDC + ADB = 180 (definition of linear pair), and ADB = 90 (given).
BDC = ADB because 90 = 90
Overall, the two triangles are congruent by SAS.

Answer: 2/5</h3>
This is because there are 20 women out of 50 people total (30+20 = 50).
So 20/50 = 2/5
This converts to the decimal form 0.4 and the percentage form 40%
