Question

The perimeter of A ABC is 50 cm. Its sides AB, BC and AC are respectively 15 cm,
10 cm and (x + 4) cm. Find the value of x?
​

Answer 1

Answer:

x = 21 cm

Step-by-step explanation:

Perimeter of Triangle ABC = 50cm.

       Perimeter of Triangle = Sum of all sides

            Length of Side AB = 15 cm.

            Length of side BC = 10 cm.

  Length of side CA or AC = x + 4

                                50 cm = 10cm + 15cm + x + 4

                                50 cm = 29 cm + x

                 50 cm - 29 cm. = x

                                21 cm = x
