Answer:

An inequality.

Step-by-step explanation:

This gives the range of values that y can take.

It can equal 18 or be greater than eighteen but it also could be 30 or less than thirty.

WE read the signs starting from y to the left and to the right.

So y is greater or equal to 18 and less than or equal to 30.

Hi!

Your answer is 52.

To start off, let's start with some facts that will help us solve this:

Supplementary angles are two angles whose angle measures add up to 180 degrees. You can know that they are supplementary because they can be connected by a straight line.

Triangles (all of them) have angles that add up to 180 degrees.

We can start by using supplementary angles to solve. See where the angle of 67 degrees is? The one to the right of it is supplementary to it since they are on a straight line. That means their sum adds up to 180 degrees:

$67 +?=180$

$?=113$

That angle is 113 degrees.

Now, we have 2 out of 3 angles in the triangle. Since we know that triangles' angles add up to 180 degrees, we can make an equation:

$15+113+x=180$
