Solve for x. Can someone help me fast!

Mathematics
1 answer:
iVinArrow [24]3 years ago
4 0

Answer:

\displaystyle 55° = x

Step-by-step explanation:

Angles <em>B</em><em> </em>and<em> </em><em>C</em><em> </em>form a straight angle, so you set both expressions equal to 180°:

180° = (2x + 15)° + x°

180° = 15° + [3x]°

- 15° - 15°

____________

\displaystyle \frac{165°}{3°} = \frac{[3x]°}{3°} \\ \\ 55° = x

I am joyous to assist you anytime.

What is the surface area of the cone? Express your answer in terms of π.b
weeeeeb [17]

Given:

Radius of the cone = 5 ft

Slant height of the cone = 21 ft

To find:

The surface area of the cone

Solution:

Surface area of cone formula:

SA=\pi r^{2}+\pi r l

where r is the radius and l is the slant height.

SA=\pi \times 5^{2}+\pi \times 5 \times 21

SA=\pi \times 25+\pi \times 105

SA=25 \pi+ 105 \pi

SA=130 \pi

The surface area of the cone is 130π square feet.

How much fabric is needed to create the lateral faces of the tent?
jek_recluse [69]
Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40

40+89.6=129.6

the area of the bottom is 7*8=56

the total area is 129.6+56=185.6

I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice. 
I'd suggest 185.6, the total surface area.
