Answer:

x=36

Explanation:

The angles in a triangle must add to 180 degrees.

Therefore,

x+65+79=180

Add 65 and 79

x+144=180

We want to solve for x. In order to do this, we have to get x by itself. 144 is being added to x (+144)The opposite of addition is subtraction, so subtract 144 from both sides(-144)The +144 and -144 will cancel out, and leave x by itself.

x+144-144=180-144

x=180-144

x=36

Let’s check our answer. Add all the angles together, and make sure they equal 180 degrees.

x+65+79

We know x is equal to 36, so we can substitute it in

36+65+79

180

The 3 angles add to 180, so we know that x=36
