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.
Volume = 1/3 * area of base * height
= 1/3 * 11^2 * 12
= 484 cm^3
