Which equation is correct regarding the measure of ∠MNP?
Evgen [1.6K]

Answer:

The measure of anle MNP is

  • m ∠ MNP =  (x - y)/2

Explanation:

The image attached shows the figure corresponding to this question.

The <em>angle MNP</em>, wich is also the angle LNP, is formed by the intersection of a secant and a tanget to a circle.

Then, you can use the theorem:

  • the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.

The major arc formed is identified with the letter x and the minor arc is identified witht he letter y. Thus, the measure of the angle MNP is half the differenc x - y:

  • m ∠ MNP = (x - y)/2
