Answer:

Step-by-step explanation:

 To find the size of YXZ we should use some trigonometry but first let's find the length of YZ

  • The Pythagorian theorem :

(XZ)²+(ZY)²=(YX)²

YX=\sqrt{20^{2}+8^{2}  }

    =4\sqrt{29}

<h2>We khow that sin(YXZ)=(YZ)/(YX)</h2><h2>                                         = 20/(4\sqrt{29})</h2><h2>                                         = 5/\sqrt{29}</h2>
  • using a calculator we get (YXZ)=  68°

A taxicab charges $3.00 per person
Delicious77 [7]

Answer:

I believe the answer would be 20 miles max for one passenger.

Step-by-step explanation:

This is because if you create an equation out of this, knowing that only one passenger will be riding, you will get:

$3.00+$1.25x=$28       ($3 added too $1.25 times the number of miles (x) which equals the total amount you have ($28)).

x being the number of miles (so we need to calculate for x)

$3 + $1.25x = $28

-subtract 3 on both sides-

$1.25x=$28-$3

$1.25x=$25

-divide by 1.25 on both sides-

x=$25/$1.25

x=20 miles

Not sure if all calculations are correct, but I hope this helps :)!
