Since the **value** of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the **value of X**.

Beside that, how do you find the value of X outside a circle?

Even in the case, how do you find the value of the variable in a circle?

Well, how do you find the value of x in chords and arcs?

How do u solve for x?

Isolate **x** by dividing each term by the **x** coefficient. Just divide 3x and 9 by 3, the **x** term coefficient, to **solve for x**. 3x/3 = **x** and 3/3 = 1, so **you**'re left with **x** = 1.

By the **inscribed angle** theorem, the measure of an **inscribed angle** is half the measure of the intercepted arc. The measure of the central **angle** ∠POR of the intercepted arc ⌢PR is 90°. Therefore, m∠PQR=12m∠POR =12(90°) =45°.

circumference

A circle is 360° all the way around; therefore, if you divide an **arc's** degree **measure** by 360°, you **find** the fraction of the circle's circumference that the **arc** makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the **arc**.

If two **chords** of a **circle** are **congruent**, then they determine central angles which are equal in measure. If two **chords** of a **circle** are **congruent**, then their intercepted arcs are **congruent**. Two **congruent chords in a circle** are equal in distance from the center.

Two **circles** are **congruent** if they have the same size. The size can be measured as the radius, diameter or circumference. They can overlap.
