Use Structure Write and solve an equation to find the value of x. What is the measure of

each labeled angle?

stethere all not eveanp-by-step explanation:

the answer is d

hope this

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
