Given:
Opposite angles of the parallelogram are (3x+3)degrees and (4x-4)degrees.
Required:
To find the value of x.
Explanation:
We know that the opposite angles of the parallelogram are equal.
So the given angles will be equal.
[tex]\begin{gathered} (3x+3)\degree=(4x-4)\degree \\ 3x+3=4x-4 \\ 3+4=4x-3x \\ x=7\degree \end{gathered}[/tex]Final Answer:
The value of x is 7deegrees.
