Can anyone explain to me how to do this?

Ipatiy [6.2K]

Answer:

x = 12

Step-by-step explanation:

The angle formed by two chords is half the sum of the intercepted arc angles.

m∠UST = ½ (mVL + mUT)

5x + 18 = ½ (66 + 8x − 6)

10x + 36 = 60 + 8x

2x = 24

x = 12

Left to Right

Algebra I

Coordinates (x, y)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (2, 1)

Point (6, 7)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(6 - 2)^2 + (7 - 1)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{4^2 + 6^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{16 + 36}$
[√Radical] Add: $\displaystyle d = \sqrt{52}$
[√Radical] Simplify: $\displaystyle d = 2\sqrt{13}$
