If angle MNO is a rectangle, and MO = 54 , what is the length of overline NP ? A. 34 B. 22 C. 18 D. 108 E. 27 F. Cannot be deter
cricket20 [7]

Answer:

Option (E)

Step-by-step explanation:

LMNO is a rectangle.

MO = 54

By the property of a rectangle,

1). Diagonals are equal in length.

2). Diagonals equally bisect each other.

Since, MO = LN

Therefore, LN = 54

Since, NP = \frac{1}{2}(LN)

NP = \frac{54}{2} = 27

Option (E) will be the correct option.

Angle FEDwith angleF=90degree, ED=36, and FE=22, calcularé the measures of the unknown angles and the unknown side length of the
Flauer [41]

Answer:

\angle D=37.7^{\circ}

\angle E=52.3^{\circ}

FD\approx 28.5

Step-by-step explanation:

Please find the attachment.

We have been given that angle FED with angle F=90 degree, ED=36, and FE=22. We are asked to find the unknown angles and the unknown side length of the triangle.

We will use sine to solve for angle D as:

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{sin}(D)=\frac{22}{36}

D=\text{sin}^{-1}(\frac{22}{36})

D=37.66988696^{\circ}

D\approx 37.7^{\circ}

Therefore, measure of angle D is 37.7 degrees.

Now, we will find measure of angle E using angle sum property.

m\angle E+m\angle F+m\angle D=180^{\circ}

m\angle E+90^{\circ}+37.7^{\circ}=180^{\circ}

m\angle E+127.7^{\circ}=180^{\circ}

m\angle E+127.7^{\circ}-127.7^{\circ}=180^{\circ}-127.7^{\circ}

m\angle E=52.3^{\circ}

Therefore, measure of angle E is 52.3 degrees.

We will use Pythagoras theorem to solve for side FD as:

FD^2+EF^2=ED^2

FD^2+22^2=36^2

FD^2+484=1296

FD^2=1296-484

FD^2=812

FD=\sqrt{812}

FD=28.495613697\\\\FD\approx 28.5

Therefore, length of side FD is approximately 28.5 units.

Find the value of each variable. X and y. 26 30
meriva

Answer:

x = 13 and y = 13√3

Step-by-step explanation:

Recall that sin Ф = opposite side / hypotenuse, and that

                   cos Ф = adjacent sice / hypotenuse.

if we recognize that the angle Ф is 30° here, then we know that:

x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.

and....

y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3

In summary, x = 13 and y = 13√3

Solve for x: x - 10 = -12
andre [41]

Answer:

x = -2

Step-by-step explanation:

Step 1: Add 10 to both sides.

  • x - 10 + 10 = -12 + 10
  • x = -2

Step 2: Check if solution is correct.

  • -2 - 10 = -12
  • -12=-12

Therefore, x = -2.
