PLEASE HELP LAW OF COSINES

chubhunter [2.5K]

The Law of Cosine states
cos $C=(a^2+b^2-c^2)/2ab$

so plugging in the numbers gives us

cos $J=(13^2+19^2-11^2)/2(13*19) = 409/494$

We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos $(409/494)=34.11$
rounding your answer will give you 34°

Delia went to the market to buy 4 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 bill and received $3.

Mekhanik [1.2K]

Answer:

$4.57. Hope this helps :)

Step-by-step explanation:

20+5=25

then you do

25-3.67= $21.33

you then divide that by the number of pounds she bought.

21.33/4= 5.3325

round that to the hundreths place and you get $5.33

so she paid $5.33 for a pound
