Answer:
x = 10
Explanation:
In a parallelogram, each two opposite angles are equal in measure.
In the given parallelogram ABCD, we can note that angles A and C are opposite angles. This means that the measures of these two angles are equal.
Therefore:
∠A = ∠C
2x + 50 = 3x + 40
50 - 40 = 3x - 2x
x = 10
We can check:
angle A = 2(10) + 50 = 70°
angle C = 3(10) + 40 = 70°
They are equal
Hope this helps :)
