Answer -
In тИЖABC, тИаA = 40┬░, тИаB = 60┬░
But тИаA + тИаB + тИаC = 180┬░
┬а
тЗТ 40┬░ + 60┬░ + тИаC = 180┬░
тЗТ тИаC = 180┬░ = (40┬░ + 60┬░)
= 180┬░ тАУ 100┬░ = 80┬░
тИ╡ тИаC = 80┬░, which is the greatest angle and
тИаA = 40┬░ is the smallest angle
тИ┤ Side AB which is opposite to the greatest angle is the longest and side BC which is opposite to the smallest angle is the shortest.
