as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solve for "y".
Answer:
21: 37
They are the opposite side exterior angles
22: 40
23: 126
They are the opposite side exterior angles
24: 1
25: 12
90 - 48 = 42
42 = 3x + 6
36 = 3x
12 = x
26: 41
180 - 139 = x
41 = x
27: 140
180 - 40 = 140
28: 68
90 - 22 = 68
29: False
Complementary angles add up to 90 degrees
Hope this helps!
I wanna say standard but I’m sure. Sorry if I’m wrong I’m in precal now. Not algebra
