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:
Step-by-step explanation:
<u>Given inequality:</u>
<u>Solve it:</u>
The graph includes the number line to the right of 5 and the 5 is included, so this point is represented by a full dot.
Correct choice is A
Answer:
Step-by-step explanation:
y=-1
because when y = - 1,
it is an equation of x axis.. hence it will parallel to x axis....
Answer:
b= -1.6
When you do inverse operations, (-1)-0.6= -1.6
Eliminate parentheses using the distributive property.
... -1 -7g +42 +6g = 36
... 41 -g = 36 . . . . collect terms
... 41 -36 = g . . . . add g-36 to both sides
... 5 = g . . . . . .. . . your answer
