Answer:
x = 6
Step-by-step explanation:
∡J = ∡K and ∡M = ∡L
because this is an isosceles trapezoid
∡J + ∡M = 180°
because angles at opposite bases are supplementary
then ∡J + ∡M = 180°
∡J = (7x + 2)°
∡M = ∡L = (25x - 14)°
so:
(7x + 2 + 25x - 14)° = 180°
(32x - 12)° = 180°
32x = 180 + 12
32x = 192
x = 6
