4. A new runway is to be built at an airport.
The plan below shows some of the angles.
Bryn has been asked to complete the plan by finding each of the missing angles, \(x\), \(y\) and \(z\).
Diagram not drawn to scale
Calculate the size of each of the angles \(x\), \(y\) and \(z\). [3]
\(x\) = …………… ° \(y\) = …………… ° \(z\) = …………… °
