Answer:
<em> Length of guy wire is 590.6 ft</em>
Step-by-step explanation:
The complete question is
A radio transmission tower is 210 feet tall. How long should a guy wire be if it is to be attached 8 feet from the top and is to make an angle of 20° with the ground. Give your answer to the nearest tenth of a foot.
height of tower = 210 ft
8 ft fro the top leaves 210 - 8 = 202 ft to the ground
This is an angle of elevation problem
the opposite is 202 ft
hypotenuse = ?
angle is 20°
using sin ∅ = opp/hyp
sin 20° = 202/hyp
0.342 = 202/hyp
hyp = 202/0.342 = <em>590.6 ft this is the length of the guy wire</em>
The only ones that are functions are the ones where the y-coordinate does not repeat. B and D
- Circumference = 6cm
- Let the radius be r.
- Therefore, 2πr = 6 cm
- Given, height = 8 cm.
- Therefore, curved surface area of the cylinder = 2πrh
- = (6 × 8) cm^2
- = 48 cm^2

<u>4</u><u>8</u><u> </u><u>cm^</u><u>2</u>

PS on my program it shows me that answers to study it so I know this is right
Answer:
32
Step-by-step explanation:
ok if it was a normal rectangle =
8 x 6
but the middle part takes 4 from the middle
since there are 2 rectangle
4/2 = 2
since there are lines
6 x 2 = 12 + another 12 since the rectangle on the bottom is the same as the top
24 + ...
6 - 4
2 x 4 = 8
24 + 8 =
32
