Answer:

Step-by-step explanation:
A = (-123)+77+(-257)+23-43
A = -46+(-257)+23-43
A = -303+23-43
A = -280-43
A = -323
Hope this helps
We have two sides and one angle opposite to one of the known sides.
Begin with applying the Law of Sines to find angle A:

= <span>

Then, solve for sin A:
</span>sin A =

Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17
We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.
6 out of 20=what percent?
6/20=x%
percent means parts out of 100
x%=x/100
6/20=x/100
time both sides by 100
30=x
answer is 30% passed
100-30=70
70% is answer
The answer would be 21 because its the same length as the other side.
Your answer would be 5.10... Hope this helps :)
