Answer:

x=31

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees.

So, 2x+28=90.

To solve:

1. Subtract 28 from both sides

2x=90-28

2x=62

2. Divide both sides by 2

x=62/2

x=31

Answer:

so ABD is equal to 90 degrees. all you have to do is subtract angle CBD (which is 38 degrees) from angle ABD (which is 90 degrees). this would mean that 2x = 52. you then solve for x which means x = 26.

Step-by-step explanation:

90 - 38 = 52

2x = 52

x = 26
