Both triangles are rightangled triangles. Thus u can use Pythagoras theorem to solve the question. If u do not know what the theorem is about, see drawing.. dw:1329221023919:dw the theorem states that, the 3 sides are related by the equation. a^2 +b^2 = c^2 Thus back to the question.. DA = sqrt (8^2 + 10^2 ) =12.8 DC = sqrt (8^2 + 12^2) =14.4
