Answer 2

Answer:

I think i gave u answer for 21 and 23 but ill give ya again :)

21.) x = 0

22.) x = 8

23.) x = 0

24.) x = 12

Step-by-step explanation:

21.) x + 12 = 12

=> x = 0

22.) x - 1 = 7

=> x = 8

23.) 12 + 2x = x + 12

=> 12 + x = 12

=> x = 0

24.) 2x - 14 = 10

=> 2x = 24

=> x = 12

(All of these equations are set equal to their opposite side on the same figure since both the sides are parallel and congruent)

Hope this helps!
