Work out the size of angle x.
33°
20°
165°

X = 52°

Step-by-step explanation:

it all has to add up to 360°

33 + 20 + 165 = 218

The other missing angle is an acute angle witch means its 90°

218 + 90 = 308

360 - 308 = 52°

x = 52°

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
