If cos ø = -4/7 what are the values of sin ø and tan ø

tan=5,5

sin=0,98

Sry when Its wrong

sin• = √13/7

tan•= -√13/4

Step-by-step explanation:

sin2•+ cos2• = 1

sin• = √1-cos2•

sin•= √1-(-4/7)2

sin•= √1-16/49

sin•= √ 49-16/49

sin•= √ 13/ 49

sin•= √13/7

tan• = sin•\cos•

= √13/7/-4/7

= -√13/4

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
