Answer:

Step-by-step explanation:
we know that
The formula of law of cosines is equal to

where
a, b and c are sides. C is the angle opposite side c
In this problem we have

substitute the given values






Answer:
Angle F, or 1; see below
Step-by-step explanation:
When two triangles are congruent, everything about them is equal. Angle C is congruent F because they are in the same position on the triangle.
Answer:
Slope is 3
Y- intercept is -4
Doesn't pass through zero.
Linear
Give me options and I can give a better answer :)
Answer:
Yes. Juan will break even because 16 and -16 are a zero pair. -16 is the additive inverse of 16. So the sum will be 0.
