Answer:
No
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.
31² = 961
16² + 30² = 256 + 900 = 1156
Since 961 ≠ 1156 then the sides do not form a right triangle.
First number assume A
Second number assume B
A= 1/3B ==> B= 3A
A+B = 48 ==> A+ 3A= 48
4A= 48 ==> A= 12
B= 3A= 36
