The question, in short

Measure the angle x shown between two straight lines in the diagram, then name the type of angle that measures 83°.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

Use a protractor to measure the size of angle x in the diagram.

  1. 1Put the protractor's centre on the vertex and its zero line along one arm
  2. 2Read the scale at the other arm: x = 83°

Answer83 (accept 81 to 85)

Part (b) · 1 mark

Given that angle x is 83°, state the mathematical name for this kind of angle.
