  1. can we use the law of cosignes in the isosceles triangle question? that way, we could find which sides sum up to 180 degrees in angles, so that the answer an be option c instead of option e?

  2. in the question what is the value of integer z, the b statement is Y is not a prime number so why 2 is the correct number as it s a prime number? i really get confused on this question if you can give me more clue. thank you

  3. is K a primera number?

    K= 10! + m .. where 1<m<8..

    how do you know the answer.. I tried with a different number like

    k = 3! + m , where 1<m<8..
    k= 6+5
    k=11…prime number
