1) A circle has centre C.
RS is a chord of the circle.
R is (-1, 6).
Y (2, 3) is a point on RS such that angle CYR = 90 degrees.
Work out the co-ordinates of S.
2) APB is a triangle in a circle.
AB is a diameter.
A is (k, 5)
P is (3, 8)
B is (7, 2)
Work out the value of k.
3) PTQ is a tangent.
T (3, -4) is a point on the circumference of the circle x^2+y^2=25
Work out the equation of the tangent PTQ.
Give your answer in the form y= mx+c
4) A circle intersects the x axis at (-2, 0) and (6, 0).
The centre of the circle is (a, 3).
Work out the equation of the circle.
I AM STUCK ON THESE QUESTION ON MY FURTHER MATHS HOMEWORK. PLEASE ANSWER THESE WILL FULL WORKINGS AND EXPLANATIONS PLEASE, THANKS YOU
