What is m CD ?
Plzz help

Answers

Given:

Arc(AB) = 78 degrees

Measure of angle CMD = 106 degrees

To find:

The measure of arc CD.

Solution:

Secant intersection theorem: If two secant of a circle intersect each other inside the circle, then the intersection angle is the average of intercepted arcs.

Using secant intersection theorem, we get

[tex]m\angle CMD=\dfrac{1}{2}(Arc(AB)+Arc(CD))[/tex]

[tex]106^\circ=\dfrac{1}{2}(78^\circ+Arc(CD))[/tex]

Multiply both sides by 2.

[tex]212^\circ=78^\circ+Arc(CD)[/tex]

[tex]212^\circ-78^\circ=Arc(CD)[/tex]

[tex]134^\circ=Arc(CD)[/tex]

Therefore, the measure of arc CD is 134 degrees and the correct option is C.

What is a solution set to an inequality or an equation?

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.

Any real number can be represented in two dimensions using a number line. Any number on the number line with a solid circle next to it refers to include that number followed by the rest of the values, and any number with a hollow circle refers to exclude that value from the list before the rest of the values.

The solutions represented by number line 1 are those where: n > -3.

Using special techniques, number lines are used to represent real numbers. It was Illustrated in number line 1.
