Lee +3 = carla
x + 3 = 8
8-3 = 5
Lee checked out 5 books.
Let's see what we can fill in here.
<ACE = 130
180 - 50 = 130
Now that we have two sides and an included angle, we can use the Law of Cosines.
Law of Cosines: c^2 = a^2 + b^2 - 2ab(cos(C))
Let's plug in what we know and solve!
c^2 = 40^2 + 38^2 - 2(40)(38)(cos(130))
R = 70.69706
Hope this helps!! :)

Answer:
I think its 7 but im not sure
Answer:
y² - 4
Step-by-step explanation:
Give the expression :
"the square of y decreased by the quotient of 28 and 7"?
Expressing Mathematically ;
Square of y = y²
Quotient of 28 and 7 is obtained by taking the division of 28 by 7
Dividing 28 by 7 ; 28/7 = 4
Hence, decreasing y² by 4 ; we have ;
y² - 4
