Question

Find the value of X.

Answer 1

well you need to use the ratio of corresponding sides in similar triangles

if you split the triangles you get



you need to find y 1st

so using ratio of corresponding sides in similar triangles being equal you get

\[\frac{2}{y} = \frac{y}{12}\]

so

\[y^2 = 24\]

find y,

then find x using pythagoras' theorem.

hope it helps
