Question

Solve for x3x + x=x=3x=we are using sumplementary angles to find the answer.

Answer 1

• x+3x=180°

,

• x=45°

,

• 3x=135°

Step-by-step explanation:

From the diagram

3x and x are on a straight line, they are therefore supplementary.

`3x+x=180^0`

We solve the equation above for x.

`\begin{gathered} 4x=180^0 \\ x=(180)/(4) \\ x=45^0 \end{gathered}`

Therefore:

`3x=3*45=135^0`
