Answer:
B) 81°
Step-by-step explanation:
∡1 ≅ ∡5 because they are corresponding angles
∡5 ≅ ∡7 because they are vertical angles
therefore, ∡1 ≅ ∡7
since the angles are equal we can create the following equation:
3x + 18 = 2x + 39
x + 18 = 39
x = 21
∡7 = 2(21) + 39
∡7 = 42 + 39
∡7 = 81

Y – 3x = 7
y -3x +3x = 7+3x
y = 7+3x
21 + 9x = 3y
21 + 9x = 3(7+3x)
21 + 9x = 21 + 9x
The answer is B.There are an infinite number of solutions.
