I think I have part A but I'm stuck on B and C (a) The coordinate (-1,2) defines the centre of a circle.

The coordinate (9, -22) lies on the circumference of this circle

Find the equation for this circle.

(b) Find the tangent to the circle at the point (9, -22).

(c) Find the area of the triangle made with your tangent and the axis.

I don't know the answer but search iron gogle

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
