<p>I have no ideal on how to solve it, so if anyone can help me, i’ll appreciate it</p>

<p>The answer is 6.25</p>

2

<p>Since radius is 5, OP (from origin to point P) is 5. Because P is (k,4), a right angle triangle (with sides 3,4 and 5) is formed. K is therefore 3 (x coordinate of p).</p>

<p>Since slope of OP is 4/3, slope of the line is -3/4.</p>

<p>y= -3/4x + c
at P (3,4)
4= -3/4 (3) + C
c= 6.25</p>
