Let the co-ordinates of one vertex of \(\triangle A B C\) be \(A(0,2, \alpha)\) and the other two vertices lie on the line \(\frac{x+\alpha}{5}=\frac{y-1}{2}=\frac{z+4}{3}\). For \(\alpha \in Z\), if the area of \(\triangle A B C\) is 21 sq. units and the line segment \(B C\) has length \(2 \sqrt{21}\) units, then \(\alpha^2\) is equal to š²PW App Link - https://bit.ly/YTAI_PWAP šPW Website - https://www.pw.live
