Question

Find c so that(5,12,c) become pythagorean triplet

Answer 1

C is 13 as square of 5= 25 and 12 = 144 the angle of phythogorean triangle is 90°
And hence the square of addition of two sides gives the square of third one I mean hypotenuse so
144+25 = 169 and square of root of 169 is 13

Answer 2

By using a^2 + b^2 = c^2 we can do this question

➡ (5)^2 + (12)^2 = c^2
➡ 25 + 144 = c^2
➡ 169 = c^2
➡ (13)^2 = c^2
➡ 13 = c^2

✴Pythagorean triplet :- (5, 12, 13)
