Quadrilateral abcd is inscribed in a circle. find the measure of each of the angles of the quadrilateral.
can someone explain to me how you do this?

 m< A = 92

               m<B = 100

               m<C = 88

               m< D 80

Step-by-step explanation:

(x+2) + (x-2) = 180

2x = 180  

x=90

A= x+2=90+2=92

C= x-2=90-2=88

D=x-10=90-10=80

B=360-(92+88+80)=360-260=100

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular

124 large total

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
