Answer:
x = 21
Explanation:
In a parallelogram, each two opposite angles are equal.
In the given parallelogram ABCD, we can note that angles A and C are opposite angles. This means that they have equal measures.
Therefore:
∠A = ∠C
x + 17 = 2x - 4
17 + 4 = 2x - x
x = 21
We can check:
angle A = 21 + 17 = 38°
angle C = 2(21) - 4 = 38°
They are equal
Hope this helps :)
