In an orthonormal system, you're given the following: Point P(1,2)
Lina a=cartesian eqn:4x3y+6=0
Line b=parametric eqns:x=5+3&
y=& (real n°)
Circle z=cartesian eqn:x²+y²2x3=0
(a)Calculate the angle between lines a an b
(b)Calculate the coordinates of the point of intersection of lines a and b
(c)Calculate the distance from P to line b
(d)Find the centre C and the radius r of circle z
(e)Calculate the cartesian eqn of the tangent t to the circle z at the point T(3/5,6/5) Show that this tangent is line a
(f)M,P,N are,respectively,the points on t and z having the same x coordinates as C. Show that MT²=MP*MN
PLEASE HELP!!!
