Answer:
- [tex]\large\boxed{\sf{x=45}}[/tex]
Step-by-step explanation:
Given:
- Complementary angles of 180 degrees.
To solve:
- For x, to isolate it one side of the equation.
(3x)°+45°=180°
3x+45=180
First, subtract by 45 from both sides.
3x+45-45=180-45
Solve.
Subtract these numbers goes from left to right.
180-45=135
3x=135
Divide by 3 from both sides.
3x/3=135/3
Solve.
Divide these numbers from left to right.
135/3=45
[tex]\Longrightarrow: \boxed{\sf{x=45}}[/tex]
- Therefore, the final answer is x=45.
