const2013 [10]3 years ago
6 0

Answer:

9.42 meters

Step-by-step explanation:

diameter = 8 m

radius = 4 m

Length of arc = radius * central angle in radians

= 4 * 3\pi / 4

= 12\pi / 4

= 3\pi

= 66 / 7

= 9.42 m

Find the cosine of the angle between the planes x+y+z=0 and 4x+3y+z=1.<br><br> Answer: cosθ=
marta [7]

The angle between the planes is the same as the angle between their normal vectors, which are

<em>n</em><em>₁</em> = ⟨1, 1, 1⟩

<em>n</em><em>₂</em> = ⟨4, 3, 1⟩

The angle <em>θ</em> between the vectors is such that

⟨1, 1, 1⟩ • ⟨4, 3, 1⟩ = ||⟨1, 1, 1⟩|| ||⟨4, 3, 1⟩|| cos(<em>θ</em>)

Solve for cos(<em>θ</em>) :

4 + 3 + 1 = √(1² + 1² + 1²) √(4² + 3² + 1²) cos(<em>θ</em>)

8 = √3 √26 cos(<em>θ</em>)

cos(<em>θ</em>) = 8/√78

Answer the questions <br><br> 1.find the value of x<br> 2.find m 3.finds
zloy xaker [14]

Answer:

x = 13°

Step-by-step explanation:

m<EGF + m< FGH = m<EGH

or, 3x+6+5x-7 = 103°

or, 8x-1 = 103°

or, 8x = 103°+1°

or, x = 104°/8

or, x = 13°

Now,

m<EGF = 3x+6

= 3×13+6

= 39+6

= 45

m<FGH = 5x-7

= 5×13-7

= 65-7

= 58
