The option that needs to be corrected in this making of a that is line parallel to AB via C is known to be the second arc should be centered at C.

<h3>Why should the second arc be centered at C.</h3>

The second arc should be centered at C because as it crosses via Line C, it is seen that it was not touching or intersecting AB and so one can say that it is a  parallel to it.

Looking at the other lines, you will see that they are all touching AB and are not running parallel to it.

Therefore, The option that needs to be corrected in this making of a that is line parallel to AB via C is known to be the second arc should be centered at C.

See full question below

14. The diagonals of square ABCD intersect at E. If AE = 2, find the perimeter of ABCD.
lutik1710 [3]

Answer:

B, 8\sqrt{2}

Step-by-step explanation:

Diagonals of a square are congruent so AC= 4

using pythagorean theorem we can then do x^{2} +x^{2}=4^{2}

2x^{2} = 16\\x^{2} =8\\x=\sqrt{8} \\x=2\sqrt{2}

Then for perimeter we times the 2\sqrt{2} by 4 and get

8\sqrt{2}

Suppose whale sharks are spotted in a rectangular area off the coast of Australia. If the dimensions of this location measure 40
nydimaria [60]

Answer:

2400 miles²

Step-by-step explanation:

Given that:

Area off the coast is rectangular ;

Dimension of location :40 miles by 66 miles

The area of the location will be : the area of a rectangle ;

The area of a rectangle = Length * width

Area = 40 miles * 60 miles

Area = 2400 miles²

(Photo attached) Trig question. Thanks in advance! :)
kolbaska11 [484]

Answer:

  a) cos(α+β) ≈ 0.8784

  b) sin(β -α) ≈ -0.2724

Step-by-step explanation:

There are a couple of ways to go at these. One is to use the sum and difference formulas for the cosine and sine functions. To do that, you need to find the sine for the angle whose cosine is given, and vice versa.

Another approach is to use the inverse trig functions to find the angles α and β, then combine those angles and find find the desired function of the combination.

For the first problem, we'll do it the first way:

  sin(α) = √(1 -cos²(α)) = √(1 -.926²) = √0.142524 ≈ 0.377524

  cos(β) = √(1 -sin²(β)) = √(1 -.111²) ≈ 0.993820

__

a) cos(α+β) = cos(α)cos(β) -sin(α)sin(β)

  = 0.926×0.993820 -0.377524×0.111

  cos(α+β) ≈ 0.8784

__

b) sin(β -α) = sin(arcsin(0.111) -arccos(0.926)) ≈ sin(6.3730° -22.1804°)

  = sin(-15.8074°)

  sin(β -α) ≈ -0.2724
