यदि बिन्दु A (7,K) समद्विबाहु जिसका आधार BC है का शीर्ष हो जहाँ B = (2,4) तथा c= (6,10) हो, तो K का मान कितना होगा ? A) 6 b)3 c)4 d)5

If the point A (7, K) is the vertex of an isosceles triangle and its base is BC, where B = (2, 4) and C = (6, 10), then the value of K is find out....https://youtu.be/ZiNQfCUjlB4

If x=√((√5+1)/(√5-1)), then the value of 5x^2-5x-1 is
(1) 0 (2) 3 (3) 4 (4) 5
अगर x=√((√5+1)/(√5-1)) तो का 5x^2-5x-1 मूल्य 5x^2-5x-1 है....https://youtu.be/o6qHtFkQ9yg
