Answer:
x =6
Explanation:
angles opposite of each other in a parallelogram are congruent
∠C and ∠A are opposite from each other and it appears that they are in a parallelogram so we can assume that ∠C = ∠A
∠A = 13x - 25 and ∠C = 9x - 1
Hence 13x - 25 = 9x - 1
13x - 25 = 9x - 1
add 25 to both sides
13x = 9x + 24
subtract 9x from both sides
4x = 24
divide both sides by 4
x = 6
