The perimeter of triangle ABC is 36 cm. The length of the sides AB is 10 cm

The perimeter of triangle ABC is 36 cm. The length of the sides AB is 10 cm, the length of the sides BC is 4 cm more than the length of the sides AC?

Given:
AB = 10 cm;

BC = 4 cm more;

AC =? cm.

P ABC = 36 cm.

Let’s calculate the BC side. We know about her that she is 4 cm larger than the sun.

1) 10 + 4 = 14 (cm)

In order to find the AC, you need to subtract the sum of the lengths of the sides AB + BC from the perimeter:

2) 36 – (10 + 14) = 36 – 24 = 12 (cm)

Answer: 12 cm side length of the speaker.

Check: AB + BC + AC = P (ABC)

10 + 14 + 12 = 36 – true.
