Points A A\,A and B B\,B have position vectors (14)\begin{pmatrix} 1 \\ 4 \end{pmatrix}(14) and (52)\begin{pmatrix} 5 \\ 2 \end{pmatrix}(52) respectively
Point C C\,C has position vector (p5)\begin{pmatrix} p \\ 5 \end{pmatrix}(p5) and ABC ABC\,ABC is a straight line.
Find ppp
Point D D\,D has position vector (q5)\begin{pmatrix} q \\ 5 \end{pmatrix}(q5) and angle ABD=90∘ABD = 90^{\circ}ABD=90∘
Determine the value of qqq.
