Question

5. The hypotenuse of a right angled triangle is 25 m. If one of the other two sides is 20 m, find the
length of its third side​

Answer 1

Step-by-step explanation:

$(hypotenuse) ^{2} = \: ( \: side) {}^{2} + \: (side) {}^{2}$

$25 {}^{2} = 20 {}^{2} + (side) {}^{2}$

$225 = 400 + (side) {}^{2}$

$(side) {}^{2} = 225 - 200$

$(side) {}^{2} = 25$

$side = \sqrt{25}$

$side = 5m$

Lenght of third side is 5m.
