Point c is the center of the circle. the measure of angle acb is 3x + 120. arc ab measures 65x – 4. find the measure of arc ab.

The measure of arc AB is 126°.

Step-by-step explanation:

It is given that point C is the center of the circle. The measure of angle ACB is 3x + 120. Arc AB measures 65x – 4.

The measure of central angle is equal to the measure of arc.

Solve this equation for x.

Divide both the sides by 62.

The value of x is 2.

The measure of arc AB is

Therefore the he measure of arc AB is 126°.

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors

if the angular bisector of an triangle bisects the opposite side, prove that the other two sides are equal.
