Using the cosine ratio, the value of AD in the diagram is: 2√3π in.

<h3>How to Apply the Cosine Ratio?</h3>

If we have the following given in a right triangle like triangle ADC in the diagram:

AC = 4π (hypotenuse)

AD = ? (adjacent side)

The cosine ratio, CAH would be applied, which is:

Cos 30 = adjacent/hypotenuse

Cos 30 = AD/4π

AD = cos 30 × 4π = √3/2 × 4π [cos 30 = √3/2]

AD = 2√3π in.

The width of a rectangle is 8 cm less than its length. The perimeter of the rectangle is 52 cm.What is the width of the rectangl

astraxan [27]

Let X be width <span>of a rectangle, then
(x+8) - </span><span>length

(x+x+8)*2 = 52
x+x+8 = 52/2
2x+8 = 26
2x = 26-8
2x = 18
x = 18/2
x = 9 cm

Answer: 9 cm.</span>

Answer:

<2, <3, <4

Step-by-step explanation:

You have parallel lines cut by a transversal, so alternate interior angles are congruent. Also, alternate exterior angles are congruent. Corresponding angles are congruent.

Vertical angles are always congruent.

I'll write each congruent angle and the reason.

<2, vertical

<3, corresponding

<4, alternate exterior angle
