Perimeter of triangle ABC is 50cm, its sides AB, BC, AC are 15cm,10cm,(X+4)cm find the value of X

21

Step-by-step explanation:

the perimeter equals the sum of the 3 sides of the triangle so 50=15+10+x+4

x=50-29

x=21

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:
