Will give briniest and like it Three lines intersect at a common point. In the figure below, m∠1=x°, m∠2=2x°, and m∠3=75°.
Which equations can be used to determine the value of x? Select all that apply.

A:3x°=75°

B:3x°=105°

C:3x°=255°

D:3x°+75°=180°

E:x°+2x°+75°=180°

F:x°+2x°+3x°=360

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

D) the x-intercept represents adam's commission pay when he had zero total sales
