С In the figure below we have the 2 circles (CD) and (c) of the same center O and their radii are
R = 2cm and R2 = 4cm respectively. A straight line passing through O cuts (C) at F and A
and cuts (C) at B and E. The tangent to circle
(C:) at A cuts the circle (C) at C and D.
01) Show that (CD) is the perpendicular
bisector of [OB].
2) Determine the nature of the triangle OBC.
3) Show that the quadrilateral OCBD is a
thombus.
4) Let P be the midpoint of [CE].
a. Calculate OP and deduce that P belongs
to the circle (C1).
b. Show that D, O and P are collinear.
c. Show that (OP) is perpendicular to (CE)
and deduce that (CE) is tangent to (C1).
d. Show that (CO) is perpendicular to
(DE).

Help me pleas

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

I’m not sure about that

And i oop, gurlll he not gonna have no more left .. anna ou
