Question

Can you help me find the value of x? (Grade 10, angles)

Answer 1

Ok, so

Here we have a parallelogram:

Remember that the opposite angles are equal.

Now, the sum of all the internal angles of a parallelogram is 360°. This is:

$\begin{gathered} 6x+9x+6x+9x=360 \\ 30x=360 \\ x=12 \end{gathered}$

Therefore, x=12.
