Recall that a full angle measures 360^(∘).

Practice makes perfect

We want to find the value of x in the given figure.

Recall that the full angle around a point measures 360^(∘). We can use the angle addition postulate to write an expression for the angles. For simplicity, we will remove the degree symbol. x+x+x+x=360 Let's solve it for x.

x+x+x+x=360
