Answer:
2
Step-by-step explanation:
This can be easily understood with the triangle inequality theorem, which tells us that <em>"the sum of any two side of a triangle is always greater than the third side"</em>. Let's check:
- Is 6+9 greater than 12? Yes!
- Is 6+12 greater than 9? Yes!
- Is 9+12 greater than 6? Yes!
So, first of all, it is possible to create triangle(s). Moreover, it also says that <em>"If longest side is less than sum of the other two sides and those two sides are NOT equal, then we have two congruent triangles which are mirror images of each other"</em>.
Hence we can create 2 triangles.
Answer:
38.5
Step-by-step explanation:
to find the area of the triangle, you can do 11 x 3 ÷ 2 = 16.5
then you find the area of the triangles: 3 x 3 = 9
and 3 × 11 = 33
then you add them all to find a total area of 38.5
Answer:
{0}
Step-by-step explanation:
{0} is not because 0 is not an element of set {1, 2, 3}
The null set is a subset of every set, so Ø is.
A set is a subset of itself.
