Need or i wont get coochie pls 30 points

let x be a point and join point c

when XC // AL // BK

∠LAC+∠ACX = 180 (int. angle, XC//BK)

∠ACX = 60

then ∠ACX + ∠BCX = 80

∠BCX = 80 - 60 = 20

∠BCX + ∠B = 180 (int. angle, XC//BK)

∠B = 180 -20 = 160

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

answer: c.
