Answer:
The answer is option A.
<h2>50 degrees</h2>
Step-by-step explanation:
To find angle C we use the cosine rule
That's
AB² = AC ² + CB ² - 2(AC)(CB)cos C
AC = 7.5
AB = 6
CB = 6.5
6² = 7.5² + 6.5² - 2(7.5)(6.5)cosC
36 = 56.25 + 42.25 - 97.5cos C
36 - 98.5 = - 97.5 cos C
-62.5 = - 97.5 cos C
cos C = -62.5 / - 97.5
C = cos ^-1 25/39
C = 50.1
The final answer is
<h3>C = 50°</h3>
Hope this helps you.
ANSWER
Find out the how many milliliters of water did coach Kelly put in each cooler.
To proof
let us assume that the water put in the each cooler be x.
As given
Coach Kelly bought 32 L of water
she divied the water equally between 8 coolers
1 litre = 1000 miilitre
solving the above
x = 4000 millitre
therefore 4000 milliliters of water did coach Kelly put in each cooler.
Hence proved
8,16,24,32,40
All you have to do is replace the n in 8n with the sequance number you're looking for
like for instance:
8(1)=8
8(2)=16
Above statement can be represented as :
