find the measure of angle x in the figure below:

15°
25°
30°
60°

The measure of x is 30°

Step-by-step explanation:

∵ The sum of angles in any Δ = 180°

∵ two angles have measure 75°

∴ The measure of the third angle = 180° - (75° + 75°) = 30°

∴ m∠x = 30 vertically opposite angles

the answer is d. 75%

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.
