Question 1 The numbers 11, 60, and 61 are a Pythagorean triplet.
Checking if: 11^2 + 60^2 = 61^2
121 + 3600 =3721 and 61^2 is also 3721.
Question 2 Determine the value of A for: 6^2 + A^2 = 12^2
36 + A^2 = 144
A^2 = 144 - 36 = 108
A = Square root of 108 and that is about 10.4
Question 3
13^2 = 10^2 + base^2
169 = 100 + base^2
169 - 100 = base^2
69 = base^2
base = square root of 69 and that is about 8.3
