Sin75° = Sin(30° + 45°)
= Sin30°.Cos45° + Sin45°.Cos30°
= 1/2 . √2/2 + √2/2.√3/2
= √2/2 ( 1/2 + √3/2 )
= √2/2 ((1+√3 ) /2 )
= (√2 + √6 )/ 4

Hannah would need 4 boxes
8x12 to find out how many colored pencils in each box you would get 96 then divided that by 350 to see how many boxes you would need you would get 3.645... and so on you would need to round up since Hannah needs 350 she can’t have less but she can have more therefore Hannah needs 4 boxes of pencils
Answer:
5
Step-by-step explanation:
Let :
x(1) be 2
y(1) be 5
x(2) be -2
y(2) be 2
We know that distance between any 2 points is equal to:-
![\sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%7B%28x%282%29%20%20-%20x%281%29%20%29%7D%5E%7B2%7D%20%2B%20%20%28%7By%282%29%20-%20y%281%29%29%7D%5E%7B2%7D%20%7D%20)
So using the above formula ,
![\sqrt{ {( - 2 - 2)}^{2} + {(2 - 5)}^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B%28%20-%202%20-%202%29%7D%5E%7B2%7D%20%2B%20%20%7B%282%20-%205%29%7D%5E%7B2%7D%20%20%7D%20)
![= > \sqrt{ {( - 4)}^{2} + {( - 3)}^{2} }](https://tex.z-dn.net/?f=%20%20%3D%20%20%3E%20%5Csqrt%7B%20%7B%28%20-%204%29%7D%5E%7B2%7D%20%2B%20%20%7B%28%20-%203%29%7D%5E%7B2%7D%20%20%7D%20)
![= > \sqrt{16 + 9}](https://tex.z-dn.net/?f=%20%20%3D%20%20%3E%20%5Csqrt%7B16%20%2B%209%7D%20)
![= > \sqrt{25} = 5](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%20%5Csqrt%7B25%7D%20%20%3D%205)
