Question

What is the value of x? R x+820 P Q

Answer 1

Since we're working on a circumference, the sum of all the angles must be 360°

This way,

`85+3x+73+x+82=360`

Solving for x :

`\begin{gathered} 85+3x+73+x+82=360 \\ \rightarrow240+4x=360 \\ \rightarrow4x=120 \\ \rightarrow x=(120)/(4) \\ \Rightarrow x=30 \end{gathered}`
