Answer:
[tex]x = 45[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have that x and 3x are on a straight line
and angle on a straight line sum up to 180
In other words:
[tex]x + 3x = 180[/tex]
[tex]4x = 180[/tex]
Divide through by 4
[tex]\frac{4x}{4} = \frac{180}{4}[/tex]
[tex]x = \frac{180}{4}[/tex]
[tex]x = 45[/tex]
Hence, the measure of x is 45 degrees
