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 :)

Answer:
Solution :
********************************************
Two angles are said to be a pair of
adjacent angles if they have a common
arm and lie on the either sides of the
common arm .
***********************************************
Now ,
i ) a , b are a pair of adjecent angles .
ii ) c , d are pair of adjecent angles.
iii ) e, f are not adjecent angles .
Step-by-step explanation:
The slope is 2/3
the y-intercept is (0,6)
Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
