1.	The sum of three sides of a triangle is 16 3/5 cm.If two of its sides measure 5 7/10cm and 6 3/4 cm respectively,then find the length of the third side?
Answer» Sum of 3 sides = 16 3/5 = 83/5 cmTwo sides measure = 5 7/10 = 57/10cm 6 3/4 = 27/4cmLet third side be xSum of 3 sides = x + 57/10 + 27/4 = 83/5(4x + 228 + 270) /40 = 83/5(4x + 228 + 270)/8 = 834x + 498 = 6644x = 166x = 166/4 = 83/2 = 41 1/2 cm
