Answer:
Solution:
(i) 135°
No of sides = n
Each interior angle = 135°
(2n -4) x 90° /n = 135°
180n - 360° = 135n
180n - 135 = 360°
n = 8
Which is not a whole number
Hence, it is possible to have a regular polygon whose interiro angle is 135° .
(ii) 155°
No of sides = n
Answer:
33
Step-by-step explanation:
You find the area of each triangle and that is (4*3)/2 which is equal to 6 but because all four sides are the same size you would multiply 6 by 4 so 6*4=24 you must also find the area of the bottom and that would be 3*3= 9 then you'd add them together 24+9=33 i hope that this helps!

Answer:
19
Step-by-step explanation:
Given that for every 4 milkshakes sold we get $15.
⇒ 1 milkshake cost = 15 ÷ 4 = $3.75
So, if they made $71.25 in one hour then the number of milkshakes sold
= 71.25 ÷ 3.75
= 19
