Answer 1

Answer:

9.3 or 9 and 1/3

Step-by-step explanation:

2x+x=3x

14+7=28

3x=28

28/3=9.3 or 9 and 1/3

Answer 2

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
