Question 1 1.1
In the diagram two circles intersect in A and C. BA is a tangent to the larger circle at
point A Straight lines ATD and BCD intersect the circles in T and D, and C and D
respectively. The larger circle passes through centre of the smaller circle.
O
B.
Let B = 1
D
1.1.1 Prove that D = 180° - 2x
1.1.2 Prove that AD BD.
1.1.3Prove that TCIL AB.
(5)

correct answer:

b.(19,-2)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
