The equation that can be used to determine the value of x is Option B.
<h3>What is an Equation ?</h3>An equation is a mathematical statement formed when two algebraic expression are equated by an equal sign.
From the diagram ,
A straight line has an angle of 180 degree.
Therefore from the figure
To determine the value of x
2x + 4x = 180
6x = 180
x =30 degree
Thus the equation that can be used to determine the value of x is Option B.
