two sides of a triangle have the following measures . Find The range of possible measures for the tird side

crimeas [40]

To find the third side you would use Pythagorean theorem which is a²+b²=c².

A and B being the 2 legs and C being the hypotenuse.

Example: ( sorry for the really odd not really a triangle, triangle...)
| \
6| \ ? 6²+9²=C²
|_______ 36+81=C²
9 117=C²
√117=10.8 (rounded)

if you need to get the leg you just fill in the numbers.

horrorfan [7]

Answer:

0.0025g/cm³

Explanation:

Given parameters:

Mass of the brown sugar = 12.9g

dimension of the sugar = 8cm

unknown:

density of the sugar = ?

Solution

Density is defined as the mass per unit volume of a substance. The expression is given below:

Density = $\frac{mass}{volume}$

We know the mass of the substance but the volume is unknown:

Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³

Density of the brown sugar = $\frac{12.9}{512}$ = 0.0025g/cm³
