Answer:
and
Step-by-step explanation:
To find the perimeter of the triangle, you have to add all the sides of the triangle. So, we get:
Combine like terms, meaning the numbers with
To find the area of the triangle, we will use the formula , where b is the base and h is the height
The base is:
The height is:
Plug and chug:
Answer:
39%
Step-by-step explanation:
converted to a percentage = 39%, or 0.39 in decimal form.
Answer:
Step-by-step explanation:
The volume of the metal cuboid = length x width x height = 16 x 8 x 3 = 16 x 24 = 384 cm^3
If this same cuboid is going to be reshaped, then
The volume of the cuboid = The volume of the cube
Therefore,
l^3 = 384
l =
l = 7.268..
l = 7.27cm ( 2dp)
Hope this helps.
Answer:
1. None of the angles
2. Is not
3. Is not
Step-by-step explanation:
We can see if the triangles are congruent by ASA (angle, side, angle)
We find ∠F in DEF by 180-(64+78)=38 and 38 doesn't equal 39 so they are not congruent.
The answer I believe is D. BC is congruent to DF
