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
