The triangle Inequality Theorem states that if the longest side is shorter than the sum of the other 2 sides, it will form a triangle.
7< 4 + 5 so it forms a triangle.
It is a scalene triangle (all 3 sides are not equal).
It makes an obtuse triangle. (To see why, click here: http://www.1728.org/triantest.htm )
Answer:
the answer would be x=3,1
Since a stop sign is an octagon it has eight sides. So the perimeter will be:
p=8x, p=perimeter and x=side length. We are told that the perimeter is equal to:
16x^2-80x so we can say:
16x^2-80x=8x subtract 8x from both sides
16x^2-88x=0 factor out 8x
8x(2x-11), since we know x>0
x=11/2
x=5.5 units
Answer:
45, 000 J o 45 KJ
Step-by-step explanation:
Recordemos que trabajo realizado = fuerza * distancia
En este caso, fuerza = peso del objeto
Por lo tanto, peso del objeto = 180 Kg * 10ms ^ 2 = 1800 N
Por eso;
Trabajo realizado = 1800 N * 25 m = 45, 000 J o 45 KJ
