In order to get toys from under the couch, Mom lifted up the couch to an angle of 31^\circ31 ∘
31, degrees. The kids still could not reach the toys. Then, she lifted it up another 15^\circ15

15, degrees, and the kids pulled out a bouncy ball, a foam dart, three rubber bands, and a Lego.
What was the measure of the total angle Mom lifted the couch?

answer: the four apples you took away.

step-by-step explanation:

4+4+2x

or

2x+8

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
