Question

, courtiers of electric right angled triangle is 25 CM if one of the remaining two side is 15 cm find the land of its third side

Answer 1

Answer:

The third side of the triangle is 20 cm.

Step-by-step explanation:

We are given 2 sides of a right-angled triangle whose sides are 25 cm and 15 cm for becoming a right angled triangle we must satisfy the condition for pythagorean triplets i.e. (h,p,b)

To solve this question we will be needing the pythagoras theorem which is $h^{2} =p^{2} +b^{2}$ where h is hypotenuse p is perpendicular and b is base

putting h=25 and p = 15 we get

$25^2=15^2 +b^2\\b^2 = 25^2 -15^2\\b=\sqrt{625-225} \\b=\sqrt{400} \\b=20$
