Answer:

m∠F = 66°

m∠D = 57°

Step-by-step explanation:

It looks like you have ...

∠D = ∠E = (4x +1)°

∠F = (5x -4)°

The sum of the angles in the triangle is 180°, so we have ...

2(4x +1) +(5x -4) = 180

13x -2 = 180

x = 182/13 = 14

Then the angle measures are ...

∠D = ∠E = (4(14) +1)° = 57°

∠F = (5(14) -4)° = 66°

m∠F = 66°

m∠D = 57°

A local carpet company has been hired to carpet a planetarium which is in the shape of a circle. If the radius of the planetariu

dem82 [27]

We are given radius = 6 yards

area of circle = pi * r * r = 3.14 * 6*6 = 113.04 yard square

cost of carpet is $14 per square yard

cost of 113.04 square yard = 14*113.04= 1582.56 dollars

Answer: cost to carpet the planetarium is $1582.56

How would I do this

Solnce55 [7]

Answer:

the ramp must be lowered

Step-by-step explanation:

Use the definition of the sine function to find the height of a ramp that is 8°.

Sine = Opposite/Hypotenuse

sin(8°) = height/8

height = 8×sin(8°) = 1.11

The height Nate's dad allows is 1.11 feet. At 1.5 feet, the ramp is too high.

The ramp must be lowered.

The midpoint of \overline{\text{AB}}AB is M(-6, -4)M(−6,−4). If the coordinates of AA are (-4, -3)(−4,−3), what are the coordina

valentina_108 [34]

Answer:

The coordinates of B is (-8,-5).

Step-by-step explanation:

The midpoint of line AB is M. The coordinate of M is (-6,-4).

The coordinates of A is (-4,-3)

We need to find the mid point of B.

If M(x,y) is the midpoint of the coordinates (x₁,y₁) and (x₂,y₂). The mid point theorem is used as follows :

$M(x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

Let the mid point of B is (x₂,y₂). Put (x,y) = (-6,-4), (x₁,y₁) = (-4,-3).

$(-6,-4)=(\dfrac{-4+x_2}{2},\dfrac{-3+y_2}{2})\\\\\dfrac{-4+x_2}{2}=-6\ \text{and}\ \dfrac{-3+y_2}{2}=-4\\\\-4+x_2=-12\ \text{and}\ -3+y_2=-8\\\\x_2=-12+4\ \text{and}\ y_2=-8+3\\\\x_2=-8\ \text{and}\ y_2=-5$

So, the coordinates of B is (-8,-5).

Answer me and get brainliest<br><br><br><br>pls find the volume

aalyn [17]

Answer:

6720 ft³

Step-by-step explanation:

Volume = $\frac{1}{2}$ * base * height * length

Here the base is 14 ft, height is 24 ft and length is 40 ft

using the formula:

$\frac{1}{2}$ * 14* 24* 40

6720 ft³
