how many triangles can be made from the following three lengths: 2.7 centimeters, 8.6 centimeters, and 4.8 centimeters?
one
none
more than one

none

Step-by-step explanation:

Hi, I hope this helps, I'm in high school LOL.

Use these, they help to figure this out:

a + b > c

b is the longest side, or hypotenuse. c would be the base.

We have to make sure that c is less than what a + b is.

Plug the numbers in:

2.7 + 4.8 > 8.6

4.8 plus 2.7 is 7.5 cm.

So, 7.5 > 8.6

Obviously, 7.5 is less than 8.6 so 7.5 > 8.6 does not work at all.

That tells you that no triangles can be formed. So, it's none.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.

x/3-10=8

x/3=18

x=48
