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

step-by-step explanation:

good luck tho

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
