Answer 1

Hey there!

ASSUMING

(3x)° + 45° = 180°

3x + 45 = 180°
SUBTRACT 45 to BOTH SIDES

3x + 45 - 45 = 180 - 45

SIMPLIFY IT!
3x = 180 - 45

3x = 135

DIVIDE 3 to BOTH SIDES

3x/3 = 135/3

SIMPLIFY IT!

x = 45°

Therefore, the answer should be:

x = 45

Good luck on your assignment & enjoy your day!

Answer 2

• 
  `\large\boxed{\sf{x=45}}`

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

`\Longrightarrow: \boxed{\sf{x=45}}`

• Therefore, the final answer is x=45.
