I need help with this question (answer choices 15, 5, and 12)

1 answer:

8 0

Answer:

x = 15

Step-by-step explanation:

the opposite angles of a cyclic quadrilateral sum to 180° , then

6x + 20 + 3x + 25 = 180 , that is

9x + 45 = 180 ( subtract 45 from both sides )

9x = 135 ( divide both sides by 9 )

x = 15

Answer:

-1/16

Step-by-step explanation:

Put the values where the variables are and do the arithmetic.

1 to any power is 1, so you can ignore all of the 'a' factors. That leaves ...

1/(2b^3) = 1/(2(-2)^3) = 1/(2(-8)) = -1/16

A calculator can help you figure this out.
