In the triangle XYZ XY = 5.6 cm YZ = 10.5 cm angle XYZ = 90 Work out the length of XZ

Triangle XYZ forms a right angles triangle, so pythagoras' theorem can be used to calculate the missing side. We are given the two side length adjacent to the right angle, so we need to find the hypotenuse. Pythagroas' theorm is a2 +b2=c2 where c is the hypotenuse and a and b are the two shorter sides. so 5.62+10.52=c2c2=141.61c=11.9cm
