In triangle ABC, AB measures 25 cm and AC measures 35 cm. The inequality < s < represents the possible third side length o

Flura [38]

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

s------> the length of the third side

$25+s > 35 \\ s > 35-25 \\ s> 10\ cm$

$25+35 > s \\ 60 > s \\ s< 60\ cm$

$10\ cm < s < 60\ cm$

therefore

The answer part a) is

$10\ cm < s < 60\ cm$

we know that

the perimeter of a triangle is the sum of the length sides

In this problem

$P=25+35+s\\P=60+s$

For $s> 10\ cm$

the perimeter is equal to

$P > 60+10\\ P>70\ cm$

For $s< 60\ cm$

the perimeter is equal to

$P < 60+60\\ P$

$70\ cm < P < 120\ cm$

therefore

the answer part b) is

$70\ cm < P < 120\ cm$

Elodia [21]

289 square root = 17
17*17=289
Say 17 was length and 17 was width. L*w=289
Also, all sides of the square are the same.
