100 points, please include a correct answer with a full explanation

last one: sqrt(5)

Step-by-step explanation:

Length of AB

Sqrt[(4-0)²+(4-2)²]

sqrt(16+4)

sqrt(20)

2sqrt(5)

Length of A'B': ½ × length AB

½ × 2sqrt(5)

sqrt(5)

answer: ur v dumb

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
