Question

What is the value of x? S *+559 W 2x–71° X-30

Answer 1

As shown in the figure :

The sum of the central angles = 360

so,

`(x+55)+(2x-71)+(x-3)+55=360`

Solve the equation for x :

`\begin{gathered} x+55+2x-71+x-3+55=360 \\ 4x+36=360 \\ 4x=360-36 \\ 4x=324 \\ \\ x=(324)/(4)=81 \end{gathered}`

So, the answer is : x = 81
