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>

A mixed number is a number that has a whole number, and a fraction, so the mixed number that is equal to 7.6 is 7 6/10, simplified it would be 7 3/5
