You can double check this by doing
, making sure it equals 3.
3x+5y=16 is linear equation........
Answer:
10 units
Step-by-step explanation:

Is This Substitution?
Cause if it is, then Y = 3x - 4
Y = 4 + x
= (4, 8)
Assuming you have some angle measures, you could use the
Law of Sines to solve for the missing side lengths, which states that,

,
where a, b, and c correspond to the given sides you have, and A, B, and C represent the angles you have.
In this scenario, you would have to have the values for c (which we do), and have the angle measure of C. In addition, we would also need an angle measure that is either A or B.
Hope this helps a bit!
