A side of the triangle below has been extended to form an exterior angle of 165º. Find the value of x.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
