One side of the triangle is 12 meters, the second is 1.5 times shorter than the first; the third side is 90% of the second, find these sides
A triangle is a shape made up of three points connected by line segments. These points are its vertices, and the segments are its sides.
The length of one of its sides (side AB) is 12 meters.
Let’s find the length of the second side of the triangle BC. Since its length is one and a half times less than the length of the first, then:
BC = AB / 1.5;
BC = 12 / 1.5 = 8 m.
Find the length of the third side of the AC. Since its length is 90% of the length of the second, then:
AC = BC · 90% = BC · 0.9;
AC = 8 0.9 = 7.2 m.
Answer: the length of the second side of the triangle is 8 meters, and the third is 7.2 meters.
