8. Last week, Marcia played goalkeeper for her hockey team. She stopped 20 out of 30 shots on goal. This week, Marcia
faced 36 shots. She stopped shots on goal in the same ratio
as the previous week. How many shots did Marcia stop?

14

step-by-step explanation:

14 x 3 = 42

(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
