Answer:
£15.7
Step-by-step explanation:
32 cans x 50P = 1600p
1600p to Pounds = £26.66 (1600 divided by 60)
Remaining cans = 18 (50 - 32)
18 cans x 20p = 360p
360p to Pounds = £6 (360 divided by 60)
£26.66 + £6 = £32.66
£32.66 (Profit) - £17 (Cost of cans) = £15.66
15.66 to 3SF = 15.7

This is a same side interior angle, which means that the two angles, when added, will equal 180°
y + 72 = 180
Isolate the y, subtract 72 from both sides
y + 72 (-72) = 180 (-72)
y = 180 - 72
y = 108
A) 108°, is your answer
hope this helps
