A critic randomly selects a movie to review from 3 action movies , 4 comedies , and two dramas . What is the probability that the critic selects a comedy ?

4/9

There are a total of 9 movies to choose from. 4 of them are comedy. So the chance you will pick a comedy is 4 out of nine.

(x+3)(x+7)

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
