Answer:
<h2>S = 11.4</h2>
Step-by-step explanation:
To find s we use the cosine rule
That's
s² = SU² + ST² - 2(SU)(ST) cos S
From the question
SU = 5
ST = 13
S = 60°
Substituting the values into the expression we have
s² = 5² + 13² - 2(5)(13) cos 60
s² = 25 + 169 - 130cos 60
s² = 194 - 65
s² = 129
Find the square root of both sides
s= √129
s = 11.357816
We have the final answer as
<h3>s = 11.4 to the nearest tenth</h3>

Answer:
2 + y
Step-by-step explanation:
all you must do is add y to 2
Answer:
0
Step-by-step explanation:
Cancel out x-y to x^2-Y^2 and you get x+y-x-y which is 0
It turns out that 5% of 400 is 20.
(1/20)*400=20.
