Answer:

x=23

Step-by-step explanation:

Angle DBA in total equals 90

90=2x+14+x+7

Combine like-terms

90=3x+21

Subtract 21 from both sides

69=3x

Then, divide both sides by 3 to get your answer for x

23=x

Answer:

The equation to find the angle is

(2x+14) + (x+7) = 90

Step-by-step explanation:

We now solve for x

Group like terms

[tex]2x + x + 14 + 7 = 90[/tex]

Evaluate like terms

[tex]3x + 21 = 90[/tex]

Evaluate

[tex]3x = 90 - 21[/tex]

[tex]3x = 69[/tex]

[tex]x = 69 \div 3[/tex]

[tex]x = 23[/tex]

Therefore angle ABC is 23 + 7 = 30 degree
