Find the value of'y'from the given figure

Skills needed: Angle Geometry

Step-by-step explanation:

1) First, let's see what we should know prior to solving.

---> We have to find the value of , and looking at that diagram, we have to create an equation.

---> The angle measure of a straight line is 180 degrees, otherwise known as a straight angle (a straight angle is 180 degrees).

---> When you add , you can set that sum equal to 180. This is because the two angles marked added together make a straight line, which is a straight angle.

(Note: In geometry, ONE OF THE THINGS WE CAN ASSUME is that there is a straight line there.)

2) Now, the equation would be:

--> Combining and (3+3 = 6)

--> Dividing by 6 on both sides, to get by itself.

---> is 30, so is equal to 30.
