Choice 4 is incorrect. The angles aren’t similar nor congruent.
60% divided by 6 = 10%
660 divided by 6 =110

110 x 10 = 1100
FIRST WE ...
subtract one value to the other to see how many valued we have in between
-7 - (-2) = 5
7-2=5
Both of the lines XY AND ZW have 5 units or points in between them.
Length = 5 units
They are congruent since XY = ZW in length and essentially are the same line but at different points
Okay Let's say
2x + 3 = 45
-3 -3
----------------
2x = 42
--- ---
2 2 x = 21
