If 21 measures 110 degrees, what angles will measure 60 degrees? Check all that apply.
A. 23
B. 25
C. 24
D. 26
E. 22
F. None of the angles

none of the angles = 60 degrees

Step-by-step explanation:

Assuming M and N are parallel

<1 = <4 = <5 = <8  = 110 degrees

<1 + <2 = 180 degrees since they form a line

<2 = 180-110 = 70 degrees

<2 = <3 = <6 = <7 = 70 degrees

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
