Answer:

Step-by-step explanation:
Let the third side of the triangle be
.
We can apply the cosine rule to find
.

We evaluate to obtain;



We take the positive square root of both sides to obtain;

The correct answer is B.
Answer:800
Step-by-step explanation:
75% = 0.75
600/0.75 = x/1
Cross multiply:
0.75x = 600
Divide 0.75 to both sides:
x = 800
So the full does is 800mg.
X4 + 8 = -36
x4 = -44
x = -11
(-11)4 + 8 = -36
-44 + 8 = -36
-36 = -36
Answer:
x=142
Step-by-step explanation:
so x and 142 equal eachother because they are alternate exterior angles!
set up the equation so we can solve for x
x=142
