Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
Answer:
(x-10)° + (x + 14)° = 180°
=> x° - 10° + x° + 14 ° = 180°
=> 2x° + 4° = 180°
=> 2x° = 176°
=> x° = 176°/ 2
=> x° = 88°
Therefore the magnitude of x° = 88° (ans)
57 degrees because 180-123= 57 degrees
Answer:
5 5/6 + 55x/24
Step-by-step explanation:
I'd say 88.5 because 12 divided by 1062 is 88.5 therefor thats how many boxes youd need.
