regular hexagon made up of six equilateral triangles

A = (2 × 1.7) /2 × 6 = 10.2

or by the side length

A = 3√3/2 * 2² = 10.3

If sin theta = sqrt(2/2), which could not be the value of theta?

Nataliya [291]

The solution would be like this for this specific problem:

sin(θ°) = √(2)/2

θ° = 360°n + sin⁻¹(√(2)/2) and θ° = 360°n + 180° − sin⁻¹(√(2)/2)
θ° = 360°n + 45° and θ° = 360°n + 135° where n∈ℤ

360°*0 + 45° = 45°
360°*0 + 135° = 135°
360°*1 + 45° = 405°

<span>sin(225°) = -√(2)/2

</span>225 has an angle where sin theta= -(sqrt2)/2 therefore, the value of theta cannot be 225 degrees.

Answer:

width of the rectangle=x=4in and length of the rectangle=11in

Step-by-step explanation:

Let the width of the rectangle be x, then according to the question, length is one less than three times its width that is l=3x-1.

Now, width=b=x and length=l=3x-1, thus

Perimeter of the rectangle= 2(l+b)

⇒ $30=2(3x-1+x)$

⇒ $15=(3x-1+x)$

⇒ $15=4x-1$

⇒ $16=4x$

⇒ $x=4in$

Thus, width of the rectangle=x=4in and length of the rectangle=l=3x-1=3(4)-1=12-1=11in.

The solution to -35 x = -105 is -3. TrueFalse

Setler [38]

-35x = -105

divide -105 by -35 to get x by itself

x = 3

The answer is false because the real answer would be 3

When the sum of a number and 3 is subtracted from 10 the result is 5. What is the integer

Rashid [163]

In algebraic terms this is:

$10-(x+3)=5\\10-x-3=5\\10-x=5+3\\10-x=8\\-x=8-10\\-x=-2\\x=2$

The integer is 2.
