3. Determine which of the following pairs is an adjacent side for quadrilateral MOLE below.
yKpoI14uk [10]

Pairs which is Adjacent side for quadrilateral MOLE is given below.

Step-by-step explanation:

Given:

Quadrilateral MOLE

Pair of adjacent sides of the quadrilateral.

Adjacent sides have one vertex common.

Option A: MO and LE

These sides does not have common vertex.

MO and LE are opposite sides in the quadrilateral MOLE.

It is not true.

Option B: EO and ME

In the quadrilateral, ME is not a side.

So it is not true.

Option C: LE and OL

In the quadrilateral, OL is not a side.

So it is not true.

Option D: ML and LE

These sides have common vertex L.

Therefore ML and LE are pair of adjacent sides.

It it true.

Hence ML and LE is a pair of adjacent side for quadrilateral MOLE.

How do I solve this problem?
Lilit [14]

Answer:

The diagonal is 14sqrt(2) ft

Step-by-step explanation:

The area of a square is given by

A =s^2 where s is the side length

196 = s^2

Take the square root of each side

sqrt(196) =sqrt(s^2)

14 = s

The side length is 14 ft

Now we can use the Pythagorean theorem to find the length of the diagonal

a^2 + b^2 = c^2

The side lengths of the triangle are s = 14, and the diagonal is the hypotenuse

14^2 + 14^2 = c^2

196+196 = c^2

392 = c^2

Take the square root of each side

sqrt(392) = sqrt(c^2)

sqrt(196 *2) = c

We can separate  this into two pieces  sqrt(ab) = sqrt(a) sqrt(b)

sqrt(196)sqrt(2) =c

14sqrt(2) = c

The diagonal is 14sqrt(2) ft

Armand and Jill are 247.5 miles apart, and driving toward each other. Armand is driving at a rate of 50 miles per hour and Jill
Fantom [35]
Here, the equation would be: 50t + 60t = 247.5
They will take same time, as they started their journey at a time.
Value of t, = 247.5/110 = 2.25
So, Armand traveled = 2.25 * 50 = 112.5
Jill traveled = 2.25 * 60 = 135

According to all of that information, Your Answers would be Option B, C & E

Hope this helps!
