Question

The perimeter of angle ABC is 50 cm. It’s sides AB, BC and AC are respectively 15cm, 10cm and (x+4) cm. Find the value of x?

Answer 1

AB+BC +AC=50

15+10+(x+4 ) =50

25+x+4=50

29+x=50

x=50-29

x=21

Answer 2

perimeter of an angle = sum of all sides
50cm=15cm+10cm+(X+4)cm
50cm =29+x
50-29=x
21=x
