Isosceles trick
Not sure if I'm missing something here but... If triangle RST is an isosceles, what is angle R? 1) angle T = 100 2) angle S = 40 I thought for an isosceles, if you knew the middle angle; [180-middle angle] /2 would be each remaining angle no? Apparently the answer is NOT choice D.... Sorry I know it...
