Hello everyone I really cant figure out these questions I got for a homework finished with 90% of it just cant crack these few questions. Below is the first question Sketch(Also Attached) A and B lie on the smaller circle,D and E lie on the bigger circle and C and F are points of intersection of the two circles.ABG,FCG and AFE are straight lines.B1=x Question 1 1)Bind BD then prove: 1.1)Angle B formed by GBD=Angle E 1.2)Angle D formed by BDG=Angle A 1.3)What type of quadrilateral is ABDE?Justify your answer Question 2 Sketch(Also Attached) The diameter AG is produced to C.EC is a tangent to the circle at D,A,D,G and F lie on the circle and DC=B.AFB is a straight line and A1=x and ADCB is a cyclic quadrilateral. Question 2 2.1)Prove that AC bisects Angle A formed by BAD 2.2)Prove that DG=FG 2.3)Determine with reasons the size of Angle C2 2.4)Prove that angle G1=O2 2.5)Prove that FBCG is a cyclic quadrilateral 2.6)For what value of x will DC be a tangent to the circle through F,B,C and G? Any kind of help will be much appreciated!
