Answer:
A
Step-by-step explanation:
empirical formulas are the simplest form of notation so they provide the lowest whole number ratio between the elements in a compound
Both angles are complementary and add up to 90 degrees. If you do that in an equation it should be like this:
2x + 14 + x + 7 = 90
Simplify:
3x + 21 = 90
3x = 69
X = 23
Now just plug that into angle CBD and you get:
2(23) + 14 = y
46 + 14 = y
60 = y
Angle CBD is 60 degrees
