construct a triangle XYZ in which |YZ|=6 cm angle XYZ=60° and |XZ|=9 cm measure|XY| , construct a mediator of XY and draw a circle with center X and a radius of 5cm. Measure|YA|, where A is the point of intersection of the mediator and the circle in the triangular region XYZ

4 answers

sin60°/9 = sinX/6
X = 35.3°
So, Z = 84.7°
XY/sin84.7° = 9/sin60°
XY = 10.35

not sure what a mediator XY is
you mean the median from Z to XY?
Since XY is just about exactly 10, the circle will touch XY pretty much at its center.

Maybe a bit of explanation is in order. Or maybe, knowing all the sides, you can finish up yourself.
