The law of cosines states that:
c^2=a^2+b^2-2abcosC
You already have all the values for the variables with the exception of x so:
x^2=25+100-100cos60
x=√(125-100cos60)
x=√75
x≈8.66 to nearest one-hundredth...
Taxi driver has specified ration $/miles which we assume is x (put the value here if u have)
IF taxi driver will drive 4.8+7.3 miles we can find the earnings by multiplying x by whole distance, so
cash=x(4.8+7,3)
cash=x*12.1 - its our result.

Step-by-step explanation:
Decimal = 0.3
Step-by-step explanation:
Let's solve for x.
3x−8y=7
Step 1: Add 8y to both sides.
3x−8y+8y=7+8y
3x=8y+7
Step 2: Divide both sides by 3.
3x

=
8y+7
