1) Let us find out how long the side BC of the triangle ABC has, if it is known that it is 4 cm less than the side AB, and the length of the side AB is 10 cm.
BC = 10 – 4 = 6 cm.
2) We find out the sum of the lengths of the two known sides of the triangle ABC, if AB is 10 cm long and BC is 6 cm long.
10 + 6 = 16 cm.
3) Find out what is the length of the AC side of the ABC triangle, if it is known that the perimeter of the ABC triangle is 24 cm, and the sum of the lengths of its two sides is 16 cm.
24 – 16 = 8 cm.
Answer: The length of the speaker side was 8 cm.
