3 0

In your given expression, you group x and 6y since they are in parentheses, The associative property tells you that you can change the grouping in an addition.
Don't change the order of the things you're adding, but change just the grouping.

Answer

Find out the measure, in degrees, of angle ABC .

To prove

The relationship between inscribed angles and their arcs

The measure of an inscribed angle is half the measure the intercepted arc.

The formula is

$Measure\ of\ inscribed\ angle = \frac{1}{2}\times measure\ of\ intercepted\ arc$

As given in the diagram

The measure of the intercepted arc A to B is 120°.

Put value in the formula

$\angle ABC = \frac{1\times 120^{\circ}}{2}$

∠ABC = 60°

Therefore the measure of the ∠ABC is 60° .
