The geometric means between 12 and 9 is 10.3923
The value of x is 15 degrees
Answer:
x = 4
y = 12°
Step-by-step explanation:
Since each angles are equal ,
So each angle is 60°.
=> 5y = 60°
=> y = 60/5°
=> y = 12°
Again all sides will be equal ,
=> 5x - 6 = 3x + 2
=> 5x - 3x = 6+2
=> 2x = 8
=> x = 4
It is a parallelogram because the angles are greater than 90 degrees, so, it should be correct.
