Question

answer the question correctly​

Answer 1

Answer:

10cm

Step-by-step explanation:

This is a simple question of the pythagoras theorem

the diagonal, the base and the altitude form a right angled triangle at the intersection of the base and the altitude and so it can be concluded that

$d^{2} = a^{2} + b^{2}$

$d^{2} - b^{2} = a^{2}$

$26^{2} - 24^{2} = a^{2}$

$a = \sqrt{676 - 576}$

$a = \sqrt{100}$

$a = 10$

so the altitude is 10cm
