I need help with properties of rhombus, rectangles and squares ​

Answer:

  • ∠ROK = 36°
  • ∠CKO = 96°
  • ∠C = 60°

Step-by-step explanation:

The same-side angles at each base are supplementary, so ...

  ∠ROC = 180° -120° = 60°

Because the trapezoid is isosceles, 60° also the measure of ∠C.

The angle sum theorem tells you ...

  ∠COK +∠ROK = ∠ROC

  24° + ∠ROK = 60°

  ∠ROK = 36° . . . . . . subtract 24°

__

The sum of angles in ΔCKO is 180°, so ...

  ∠C +∠COK +∠CKO = 180°

  60° +24° +∠CKO = 180°

  ∠CKO = 96° . . . . . . . . . . . . . subtract 84°

In the figure below, BD bisects ∠ABC. What is the length of AB?
dimaraw [331]

Answer:

D. 12

Step-by-step explanation:

Based on the Angle Bisector theorem, the opposite sides of ∆ABC are divided into proportional segments alongside the two other sides of the triangle, as BD bisects the <ABC. This implies that:

AB/AD = CB/CD

Substitute

AB/8 = 6/4

Cross multiply

AB*4 = 6*8

AB*4 = 48

AB = 48/4

AB = 12

Anyone know how to do these and explain so I can do the rest lol.
klasskru [66]

Answer:

Option B. m⁷/n²  is the correct answer.

Step-by-step explanation:

Identity,

xᵃ * xᵇ = xᵃ⁺ᵇ  

xᵃ/xᵇ = xᵃ⁻ᵇ

x⁻ᵃ = 1/xᵃ

It is given that,

m⁻⁶ n⁻³/m⁻¹³ n⁻¹

Using  these three identities we can write,

m⁻⁶ n⁻³/m⁻¹³ n⁻¹ = m⁻⁶ m¹³/n⁻¹n³   (since x⁻ᵃ = 1/xᵃ)

m⁻⁶ m¹³/n⁻¹n³ =m⁽⁻⁶⁺¹³⁾/n⁽⁻¹⁺³⁾ = m⁷/n²  (since xᵃ * xᵇ = xᵃ⁺ᵇ   and xᵃ/xᵇ = xᵃ⁻ᵇ)

Therefore Option B. m⁷/n² is the correct answer

The tent shown has fabric covering all four sides and the floor. What is the minimum amount of fabric needed to construct the te
Vesna [10]

Answer:

The answer is "152 ft"

Step-by-step explanation:

Please find the attached file.

The area of the square (8 \times 5=40) can be found on the foot.

The area of the triangular front will then be calculated (6\times 4=\frac{24}{2} = 12).

Since each has two sides, 24+80=104.

Therefore the multiplying the area of the bottom square (6\times 8=48)by the number of cells to get 152.
