Which angles are vertical angles in the figure shown? Select two answers.
XN
A 21 and 22
B. 22 and 23
C. 25 and 28
D. 24 and 25
E 27 and 28

B and C

Step-by-step explanation:

Vertical angles are formed when you make lines make an  x shape (or a turned x shape).  The vertical angles are, on a normally positioned x the top and bottom angle, as well as the left and right angle.  so every x has 2 vertcial angles unless the x is further split up.

So the part with angles 1. 2. 3 and 4 the top angle is 2, the bottom is 3, the left angle is 1 and the right angle is 4.  This means the vertical angle pairs are 1 and 4 as well as 2 and 3.

So in total there are 2 x shapes, so 4 pairs of vertical angles.  Here are all the vertical angles.

1 and 4

2 and 3

5 and 8

6 and 7

So from your choices you have 2 and 3 as choice B and 5 and 8 as choice C.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
