Answer:
The value of x is 9.
Step-by-step explanation:
55°
(3 x + 23)
75°
The sum of all the angles of triangle is 180°.
55 + 3 x + 23 + 75 = 180
3 x = 27
x = 9
So, the value of x is 9.

<u>Given:</u>
The width of the snack box is ![1 \frac{1}{2} \ inches=\frac{3}{2} \ inches](https://tex.z-dn.net/?f=1%20%5Cfrac%7B1%7D%7B2%7D%20%5C%20inches%3D%5Cfrac%7B3%7D%7B2%7D%20%5C%20inches)
The length of the snack box is ![2 \frac{1}{2} \ inches=\frac{5}{2} \ inches](https://tex.z-dn.net/?f=2%20%5Cfrac%7B1%7D%7B2%7D%20%5C%20inches%3D%5Cfrac%7B5%7D%7B2%7D%20%5C%20inches)
The height of the snack box is 4 inches.
We need to determine the volume of the hamsta snack box.
<u>Volume of the box:</u>
The volume of the box can be determined using the formula,
![V=L \times W \times H](https://tex.z-dn.net/?f=V%3DL%20%5Ctimes%20W%20%5Ctimes%20H)
where L is the length, W is the width and H is the height of the box.
Substituting the values, we get;
![V=4 \times \frac{3}{2} \times \frac{5}{2}](https://tex.z-dn.net/?f=V%3D4%20%5Ctimes%20%5Cfrac%7B3%7D%7B2%7D%20%5Ctimes%20%5Cfrac%7B5%7D%7B2%7D)
Simplifying, we get,
![V=\frac{60}{4}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B60%7D%7B4%7D)
![V=15 \ in^3](https://tex.z-dn.net/?f=V%3D15%20%5C%20in%5E3)
Thus, the volume of the Hamsta snack box is 15 cubic inches.
The answer is 13. You substitute the x in 2x+5 with 4, because x=4 here. That would give you 2(4)+5. 2(4) is 8, 8+5 is 13. Hope this helped!
