Answer:
C
Step-by-step explanation:
The perimeter of any shape is the distance around the edge of the shape. It is found by adding the side lengths of each side together.
Add each side length listed for the triangle part.

The Volume is 57,024.
When finding Volume you need to multiply all Numbers. In this case, we are doing 10x6x16x11x5.4
<span> f (x)= 10-x³.
f(2) means the value of the function when x=2.
So, we need to substitute 2 instead of x.
f(2) = 10 - 2³ = 10-8 =2
f(2) = 2

Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option
Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)
In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find
Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)
Hope this helps :)
