75-21=54
54/12=4.5
3 Rd side would be
13sq=12sq+xsq
Xsq=169-144
X=5
Cot theta = adj side/opp side= 5/12

Answer $39.75
Explanation: $5.49 (hamburgers) x 2 = $10.98
chicken sandwich is $6.25 and ribs are $12.99
$1.75 (sodas) x 4 = 7
$10.98 + $12.99 + $7 = $30.97
7 percent tax is $2.16 so $30.97 + $2.16 = $33.13
20 percent of $33.13 is $6.62 so $33.13 + $6.62 = $39.75
