In isoceles triangle RST, what's the measure of angle R?
Statement 1: Measure of angle T = 100
Statement 2: Measure of angle S = 40
Statement 1: Measure of angle T = 100
Statement 2: Measure of angle S = 40
IMO A..
1. If T =100 then T is the non equal angle( since no other angle can be 100 ), hence sufficient information.
