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

Evaluated to square ​
denis-greek [22]

Step-by-step explanation:

The square root of a number is a number that you can square to get it, that is, a number that you can multiply by itself to get the number. So, 2 is a square root of 4, because 2 x 2 = 4, and 3 is a square root of 9, because 3 x 2 = 9.
