help me with measurement please! if a square can become a rectangle can a rectangle become a square?
yawa3891 [41]
<span>Actually, every square is a rectangle, since the angles in a square are always right angles. That's more than saying that a square can be a rectangle; it is one.
</span><span>
And since squares are rectangles, you know that some rectangles are squares--namely, the squares are!
</span>
<span>We teach children "this is a rectangle, that is a square. The rectangle's sides are different lengths". But when you grow up, it's important to think of the square as a SPECIAL rectangle, because it is all that a rectangle is, and more.
</span>
A square is still a rectangle, but it's not just a rectangle, it's a (pedigreed) square.
In summary, yes a rectangle can be a square.

Hope this helped :)

Answer:

Step-by-step explanation:

The diagram of the triangles are shown in the attached photo.

1) Looking at ∆AOL, to determine AL, we would apply the sine rule

a/SinA = b/SinB = c/SinC

21/Sin25 = AL/Sin 105

21Sin105 = ALSin25

21 × 0.9659 = 0.4226AL

AL = 20.2839/0.4226

AL = 50

Looking at ∆KAL,

AL/Sin55 = KL/Sin100

50/0.8192 = KL/0.9848

50 × 0.9848 = KL × 0.8192

KL = 49.24/0.8192

KL = 60

AK/Sin25 = AL/Sin 55

AKSin55 = ALSin25

AK × 0.8192 = 0.4226 × 50

AK = 21.13/0.8192

AK = 25.8

2) looking at ∆AOC,

Sin 18 = AD/AC = 18/AC

AC = 18/Sin18 = 18/0.3090

AC = 58.25

Sin 85 = AD/AB = 18/AB

AB = 18/Sin85 = 18/0.9962

AB = 18.1

To determine BC, we would apply Sine rule.

BC/Sin77 = 58.25/Sin85

BCSin85 = 58.25Sin77

BC = 58.25Sin77/Sin85

BC = 58.25 × 0.9744/0.9962

BC = 56.98

Determine the equation of the circle graphed below
Irina-Kira [14]

Answer:

(x-1)^2+(y-6)^2=16

Step-by-step explanation:

The equation of a circle is given by (x-h)^2+(y-k)^2=r^2, where (h,k) is the center of the circle and r is the radius of the circle.

From the diagram, we can find the following:

  • the radius of the circle is 4
  • the center of the circle is located at (1,6)

Thus, we have:

(x-1)^2+(y-6)^2=4^2,\\\boxed{(x-1)^2+(y-6)^2=16}
