A break on the earth crust that is a result of movement or shaking refers to

A fault

Step-by-step explanation:

A fault is a crack in the Earth's crust that allows chunks of the crust to move relative to one another along its length.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

w'x is 0.
