If the goal of this question is to solve for x than the correct answer is 20. Hope this helped.
so the line is dog so we know the full line is 60 units long. The 2 parts (do and og) add up to the full length so we can make the equation:
(4x-3)+(2x+21)=60
6x+18=60
6x=42
x=7
if you need to fine do or og, just plug in x to its equation

Reflectional symmetry<span> is also called bilateral, line </span>symmetry<span> or mirror </span>symmetry. It occurs when a line is drawn to divide a shape in halves so that each half is areflection<span> of the other. Some shapes or objects, such as circles, squares and triangles, have one or more lines of </span>symmetry<span>. Mark as brainliest if u can thanks</span>
