<em></em>31\textdegree + 35\textdegree + x \textdegree= 180\textdegree<em></em>

<em></em>66\textdegree + x\textdegree = 180\textdegree<em></em>

<em></em>x\textdegree = 180 \textdegree- 66\textdegree<em></em>

<em></em>x \textdegree= 114\textdegree<em></em>

Step-by-step explanation:

the sum of all angles in a triangle is always (ALWAYS !) 180°.

180 = 31 + 35 + x = 66 + x

x = 180 - 66 = 114°

The surface area of a rectangular prism is the sum of:
Anastaziya [24]

Answer:

Surface area of prism=2(l+w)h+2(lw)

Step-by-step explanation:

We are given that surface area of rectangular prism=2(lw+lh+wh)

We have to write an expression that represents the surface area of prism.

Base of prism is made from length and width

Perimeter of base =2(l+w)

Area of base=lw=Area of top

Surface area of prism=Perimeter of base multiply by height+2 area of base

Because area of base and area of top are equal.

Surface area of prism=Ph+2B=2(l+w)h+2(lw)

One truckload is 8 cubic yards

# of truckloads needed: 720/8 = 90 truckloads

Cost: $20*90 = $1800
