If is an acute-angled triangle, in which cm and cm, which of the below is a possible length of ?
For each of the possible answers listed, is the longest side of .
For any acute-angled triangle, the square length of the triangle's
longest side is less than the sum of the square lengths of the
other two sides.
Write an inequality to show that the square length of is less
than the sum of the square lengths of the other two sides. Solve
for the value of . (Approximate to the nearest hundredth.)
Of the possible lengths provided, is the only length that 27.59 cm is greater than. Therefore .
