    @shrutipande9 is a square root of b. and if u add and b, it will result to 10

    a sqrt of b = MN a + b = 10 the distance between the centers: 6

    @shrutipande9 so it will result looking like a kite right? in which we have 6 as diagonal1 and the diagonal2 is missing. I am confused on how to find the other diagonal, there is a propery of something for this

    but for this to be a kite the diagonals need 2 be perpendicular bisectors....and we cannot just deduce it from that...

    I understood inside details (i removed the circle) like this: @eliassaab. i know that it has something to do with kites and diagonals and properties and etc etc but i am rly confused.

    But the distance between the centers of the two circles is not 5. Your original question is not 100% correct. This one is different.

    Circles A and B have radii 5 and 7 respectively, and the distance between their centers A and B is 6. If the two circles intersect at points M and N, MN = a sqrtof b. What is a+b? ORIGINAL QUESTION. @eliassaab sorry! hahaha
