2. find the volume of a triangle with side lengths 3, 4, and 5.

v=20

Step-by-step explanation:

To calculate the volume of a pyramid we will use the formula where l and w are the length and width of the base, and h is the height.

So:

l=3

w=4

h=5

applying the values in the formula

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

0.5?

hope your goes well, here's a turkey
