Answer:
x = 27°
Step-by-step explanation:
Hello!
Complementary angles add up to 90°.
Since angles A and B are complementary, we can sum up the equations to 90° and solve for x.
Solve for x
- [tex]A + B = 90\°[/tex]
- [tex]x + 2x + 9\° = 90\°[/tex]
- [tex]3x + 9\° = 90\°[/tex]
- [tex]3x = 81\°[/tex]
- [tex]x = 27\°[/tex]
The value of x is 27°.
