Idk :) but the other guy answering might be able to help you. please give me a like!
The angle between two vectors is:
CosФ = u - v / Magnitude(u) x magnitude(v)
Magnitude of u = SQRT(7^2 + -2^2) = SQRT(49 +4) = SQRT(53)
Magnitude of v = SQRT(-1^2 +2^2) = SQRT(1 +4) = SQRT(5)
u x v = (7 x -1) + (-2 x 2) = -7 + -4 = -11
cosФ = -11 / sqrt(53) x sqrt(5)
cosФ = -11sqrt265) / 265
Ф =cos^-1(-11sqrt265) / 265)
Ф=132.51 degrees.
Answer:
Step-by-step explanation:
The perimeter is all the side lengths added together
In this case, the
perimeter = x + (x+4) + (x+6) = 3x + 10
The correct answer is the first choice
Each person would get
pizza.
Solution:
Total quantity of pizza = 
Number of persons shared = 3
To find how much pizza would each person get:
Let us first convert improper fraction into mixed fraction.

Now divide the total quantity of pizza by the number persons shared.



Divide both numerator and denominator by 3.


Quantity of pizza each person get = 
Hence each person would get
pizza.
