The diameter CB of a circle is produced to a point A, from A a line is drawn to meet the circle at D and E. The line TC is the tangent to the circle at C, and this angle TCE=y°
I) calculate, in terms of y, the angle CBE, BCE and BDA
II) The diameter CB=10cm, AB=5cm and AC=6cm, calculate the length/DE/
III) A point S is on the circle such that the length /SC/ is m and the length SB is 3cm longer than SC. Show 2m² 6m-91=0 and hence find the value of m correct to 2 significant figures?
