+185 An acute isosceles triangle, ABC, is inscribed in a circle. Through B and C, tangents to the circle are drawn, meeting at point D. If \(\angle ABC = \angle ACB = 2 \angle D\) and \(\angle BAC = k \pi\) in radians, then find k.
Please help and explain ASAP, thank you!!!
+118608 Sorry about the terrible presentation,
GeoGebra froze on me and I am not about to start all over, so i just took a pic.
Now check what i have done by drawing your own pic. I could have made a mistake,
Get a equation for the angle sum of kite XBDC
Get a equation for the angle sum of triangle ABC
Solve simultaneously to find solutions for alpha and k.
