To find how much wrapping paper Taylor needs, we can find the total surface area of the rectangular prism.
= 2(18)(9) + 2(18)(4) + 2(9)(4)
= 2(162) + 2(72) + 2(36)
= 324 + 144 + 72
= 540in.²
So, Taylor will need 540in.² of wrapping paper to wrap the gift.
Best of Luck!

Answer:
The answer to your question is 13.2 ft
Step-by-step explanation:
Data
length of the ladder = hypotenuse = 16 ft
adjacent side = 9 ft
opposite side = ?
Process
1.- To solve this problem use the Pythagorean theorem
c² = a² + b²
Solve for b²
b² = c² - a²
2.- Substitution
b² = 16² - 9²
3.- Simplification
b² = 256 - 81
b² = 175
b = 13.2 ft
4.- Conclusion
The ladder is 13.2 ft resting against the building.
Answer:
32 +x+x=180(Sum of angles of a triangle)
32+2x=180
2x=180-32
2x=148
x=148/2
Therefore,X=74
