In given triangle sin 90° = 1

and we know the relation between cosine and sin is represented by

\sf\sin (x )= \cos (90-x)

Therefore,

\bf \: sin (90°) = cos ( 90-90 )\bf = cos 0°\bf \:  = 1

➪Therefore, cos 0° = 1 will be the answer...~

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
