Answer:

$x=38.5^\circ$

Step-by-step explanation:

Given that the left angle = $(3x-3)^\circ$

The right angle across from it $= 6(x-10)^\circ$

The other two angles are x and x.

We know that the sum of angles at a point equals 360 degrees.

Therefore,

$(3x-3)^\circ+6(x-10)^\circ+x+x=360^\circ\\3x-3+6x-60+2x=360\\11x-63=360\\11x=360+63\\11x=423\\x=38.5^\circ$

The value of x is approximately 38.5 degrees.
