Answer:
Step-by-step explanation:
Find the angles and sides for the triangles in the question. The questions where you're only given the angles, don't bother with the sides, because that's impossible to work out. When you're given only sides, don't bother with the angles.
Number 6, for example, requires you to know that angles NPM and RPQ are identical because they are formed by two intersecting lines, and opposite angles in intersecting lines are identical. Using the 'angles in a triangle add up to 360' rule, you can solve the rest of the question.
With questions like 7, notice how they are similar triangles and work from there.
