Answer:
x = 132
Explanation:
The sum of interior angles in parallelogram equals 360. Opposite angles are congruent. (have equal measures)
360 = 48 x 2 + 2x
360 = 96 + 2x
(subtract 96 from both sides)
264 = 2x
(divide both sides by 2)
132 = x
Check:
2x + (48 x 2) = 360
(132 x 2) + 96 = 360
264 + 96 = 360
360 = 360
