Question

please solve question number 4

Answer 1

we know that in a triangle if the square of longest side is equal to the sum of square of the remaining two side than the triangle is a right angled triangle
here,
longest side= 73
73 square = 5329...............equation 1
other two side are 45 and 55
45 square + 55 square=5050.............equation 2
from eqn 1 and eqn 2
73 square not equal to 45 square+55 square
there 45,55,73 is not a pythagorean triplet.

same for 2)
