Answer 7

use pythagoras theorem to find out. if the sum of square of the smaller length are same as the square of the larger length then they form a right angle triangle.
Like in option A the lengths given will form a right angle triangle
5^2+12^2=13^2
25+144 = 169
169 =169 .....
hope u understood!!

Answer 8
