In the diagram below, P = g + c − e and Q = a + f . What is the value of (P + Q)?
(1) BC = CD = DB = DE
(2) AB = 1/2*AE
[Reveal] Spoiler:
stat1: gives triangle BCD is equilateral implies each angle is 60..
also imples triangle BDE is isoscles with base angle 30 each and the other angle equal 120.. a and f can calulated hence
suff
stat 2: not suff..
ans A
