Answer: (-25, 5)
Step-by-step explanation:
Let
T = theta
Use the Law of Cosines to get
c^2 = a^2+b^2 - 2ab*cos(T)
<span>7^2 = 10^2+8^2 - 2*10*8*cos(T)
</span><span>49 = 164 - 160*cos(T)
-160cos(T) = 49-164
</span><span>-160cos(T) = -115
</span>cos(T) = -115/(-160)
cos(T) = 23/32
cos(T) = 0.71875 which rounds to 0.72
The final answer is C) 0.72
Answer:
27 7/12kg
Step-by-step explanation:
you take the 25 3/4 then subtract it with 13 1/2= 12 1/4
then in the problem it says he received so then you add
12 1/4 + 15 1/3 and then you get 27 7/12kg
I searched it up on symbolab I reccomend it I have been using it for a while now
Answer:
multiply 1 1/3 to 3 3/4
Step-by-step explanation:
Answer:
No,because 2 is a greater number
Step-by-step explanation:
1 1.1 1.2 1.3 1.4 1.5 & so on
so that makes 2 after/not between 1.4 & 1.5
