finding missing angles google classroom microsoft teams

Explanation:

Step1: Recall angle - sum property

The sum of angles around a point is 360°.

Step2: Set up the equation

Let the unknown angle be \(x\). We have \(x + 30+90 + 150=360\).

Step3: Simplify the left - hand side

\(x+(30 + 90+150)=x + 270\).

Step4: Solve for \(x\)

\(x=360 - 270\).
\(x = 90\).

Answer:

90
