Answer:
C ≈ 22.1°
Step-by-step explanation:
The law of cosines formula is given. Solving it for C, we find ...
C = arccos((a^2 +b^2 -c^2)/(2ab))
where a and b are the sides adjacent to the angle.
Then we have ...
C = arccos((14^2 +19^2 -8^2)/(2·14·19)) = arccos(493/532)
C ≈ 22.1°

If you have a fair number of these to do, a spreadsheet is a useful tool. There are also triangle solver apps on the web or your local smart platform that will do this, too.
Answer:
y=3/8x - 6/7
Step-by-step explanation:
slope intercept is y=mx+b where m=the slope and b=the y intercept
simply plug in the numbers given
Answer: -5/6g -2h + 4/3j
Step-by-step explanation:
Distribute -1/3 over the 5/2g, 6h, and -4j, in other words, multiply -1/3 to those other numbers and you get the answer.
Answer:
The value of f(x) when x=-1 is 0.5
Therefore 
Step-by-step explanation:
Given that y=f(x)=
to find the f(x) when x=-1 :
That is to find f(-1)
Put x=-1 in the given function f(x)=
Therefore
The value of f(x) when x=-1 is 0.5
