Can I get some help!

Using the distance formula, d = √(x2 - x1)2 + (y2 - y1)2, what is the distance between point (-10, 12) and point (5, 3) rounded to the nearest tenth?

17.5 units

10.29 units

175 units

13 units

The answer to your question is 17.5 units

Step-by-step explanation:

Data

A (-10, 12)

B (5, 3)

Formula

dAB =

x1 = -10   y1 = 12  x2 = 5  y2 = 3

- Substitution

dAB =

- Simplification

dAB =

dAB =

dAB =

Result

dAB = 17.49 units

The answer is the first choice

b is the answer that makes most sense

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
