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:
c
Step-by-step explanation:
It’s B, you go down 3 times from p and went over to the left 4 times and 3+4 =7
Answer:
Use law of Cosines or Tangent
Step-by-step explanation:
This is a SAS triangle, where you have have an angle adjacent to two side lengths. But given that it is a right triangle, you can find the hypotenuse by just using the tangent formula. You can find the quantity of any angle by applying tan= opposite side/adjacent side length.
However, lets say you want to find the opposite side, side XZ, you can use the law of cosine which basically states:
c=a^2+b^2﹣2abcos(angle number). But since it is a right triangle, just use the hypotenuse theorem which states: C^2 = A^2 + B^2
The answer for XZ would thus be: squareroot of 136 or 2(34)^1/2.
Hope this helps :)
