Question

the perimeter of triangle ABC is 62 CM its sides ab bc and ac are respectively 19 cm , 23 cm and ( x+ 5 cm) find the value of x.

I can also tell the answer the answer is 15 .
only tell the explanation​

Answer 1

Answer:

Value of x or length of AC = 15 cm

Step-by-step explanation:

Given :

Perimeter of the triangle (ABC) = 62 cm

AB = 19 cm

AC = 23 cm

AC = (x+5)cm

To find :

The value of x or the length of AC

Taken :

Use this formula to find the value of x or the length of AC -:

$\boxed{\sf{AC+BC+AB=ABC}}$

Solution :

$\leadsto\sf{x+5cm+23cm+19cm=62cm}$

$\leadsto\sf{x+28cm+19cm=62cm}$

$\leadsto\sf{x+47cm=62cm}$

$\leadsto\sf{x=62cm-47cm}$

$\leadsto\sf{x=15cm}$

So , the value of x or the length of AC is 15 cm .
