Answer:
The Value of x is 10.
Step-by-step explanation:
Consider ABCD is a Parallelogram where
∠BCA = 43°
∠CBA = 98°
∠ACD = (2x+9)
To Find:
x = ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.
In ΔABC
Now CD || BA .......opposite sides of Parallelogram is parallel
.........Alternate Angles are equal
Substituting the values we get

The Value of x is 10.
I mean, it depends what type of math you're doing but I can try!
Answer:
c
i think
Step-by-step explanation:
I think the answer to your question is It is rational and equal to 12. Hope this helps!
I'm assuming it would be the same shape? That's also assuming that it's referring to congruent shapes and angles.
