Mark scheme

Scheme	Marks	Comments
\((BD =)\ \sqrt{6^2 + 8^2}\)	M1	Allow for comment e.g. ‘Pythagorean triple is 6, 8, 10.’ or ‘6, 8, 10 is a right-angled triangle.’ (must be clear it is a triple and not just listing the 3 values from the diagram) Allow poor use of notation if intent is clear.
10	A1	does not imply M1 unless it is clear that BD = 10 (either in a statement, on the diagram or from \(\tan x = \dfrac{10}{10}\)).
45	A1	dep on all previous marks being awarded
