90
Correct answer is B
\(8^2 + (x - 2)^2 = x^2\\
64 + x^2 - 4x + 4 = x^{2}\\
x^2 - 4x + 68 = x^2\\
-4x = -68\\
-x = \frac{-68}{4} = 17\)

Describe the locus L shown in the diagram below
Locus of points equidistant from X and Y
Locus of points equidistant from X and Z
Locus of points equidistant from \(\bar{ZX}\) and \(\bar{ZY}\)

In the diagram, DE||BC, |AD| = x cm and |DB| = |AE| = ycm. Find |CE| in terms of x and y
x
\(\frac{x^2}{y}\)
\(\frac{y}{x^2}\)
\(\frac{y^2}{x}\)
Correct answer is D
\(\frac{x}{x+y}=\frac{y}{x+CE}\\
xy + xCE = xy + y^2\\
∴xCE = y^2\\
CE=\frac{y^2}{x}\)
