The product of odd numbers is always even true or false ?

Answer:

35

Step-by-step explanation:

Since its an angle bisector, both angles would be equal to each other.

3x-13=2x+3

Now you need to get x alone.

Subtract 2x from each side.

x-13=3

Still need x alone so add 13 to each side (since it negative addition)

x=16

You have x, but you need ABD

Plug 16 in for x

2(16)+3

32+3

Answer:

[tex]x=4[/tex]

Step-by-step explanation:

[tex]3.9x + 1.4 = 17[/tex]

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

[tex]3.9x*10+1.4*10=17*10[/tex]

[tex]39x+14=170[/tex]

Subtract 14 from both sides:

[tex]39x+14-14=170-14[/tex]

[tex]39x=156[/tex]

Divide both sides by 39:

[tex]\frac{39x}{39}=\frac{156}{39}[/tex]

[tex]x=4[/tex]

For triangle : A + B + C = π

⇒ A + B = π - C

⇒ cot(A + B) = cot(π - C)

⇒ [tex]\sf\dfrac{cotA\:cotB-1}{cotB+cotA}=-cotA[/tex]

⇒ [tex]\bf{cotA\:cotB+cotB\:cotC+cotC\:cotA=1}[/tex]

Now 1st part of the given expression!

⇒ [tex]\sf\dfrac{cosA}{sinB\:sinC}[/tex]

⇒ [tex]\sf\dfrac{cos(\pi-(B+C))}{sinB\:sinC}[/tex]

⇒ [tex]\sf\dfrac{-cosB\:cosC+sinB\:sinC}{sinB\:sinC}[/tex]

⇒ 1 - cotB cotC

Similarly 2nd part!

⇒ 1 - cotA cotB

Similarly 3rd part!

⇒ 1 - cotC cotA

LHS :

[tex]\circ\:\sf{3-(cotA\:cotB+cotB\:cotC+cotC\:cotA)}[/tex]

[tex]\circ\:\sf{3-1}[/tex]

[tex]\circ\:\bf{2}[/tex] = RHS

Answer:  see proof below

Step-by-step explanation:

Given: A + B + C = π                 →  A + B = π - C

                                                 →  B + C = π - A

                                                 →  A + C = π - B

Use the following Double Angle Identity:    sin 2A = 2 sin A · cos A

Use the following Cofunction Identity:    sin A = cos (π/2 - A)

Use the following Sum to Product Identity:

                                                       sin A + sin B = sin [(A + B)/2] · cos [(A - B)/2]

Answer: 1:1

Step-by-step explanation:

Answer:

RLS is a straight angle

RLT is an obtuse angle

TLS is an acute angle

TRL is not an angle

TLU is a straight angle

SLU is an obtuse angle

SLT is an acute angle

ULR is an acute angle

and ULS is an obtuse angle

Step-by-step explanation:

You really just have to look at the angles from either of the straight angles (angles that are 180°) perspective and see of they lean more to make a smaller angle by leaning towards the other end of the angle, or a large one by leaning away from the opposite end.

Answer:

the x-coordinates changes.

Step-by-step explanation:

i just done that question..

When a point is reflected over the y-axis then x-coordinate changes. so the correct option is B.

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.

If study it more, we will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.

Thus, if reflecting  a point (x,y) along x axis, then its x abscissa will stay same but y ordinates will negate. Thus (x,y) turns to (x, -y)

Similarly, if reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)

The correct option is B; the x-coordinate changes.

Answer:

40m

Step-by-step explanation:

8 times 5

The length of the boat is calculated using scale factor as 40 m.

The scale factor is a type of measurement which is used to increase or decrease the size of an object keeping its shape as the same. It can be determined by taking the ratio of the new and the original dimension of the object.

The scale factor for the given model can be calculated as,

Scale factor = Dimension of boat ÷ Dimension of model

                    = 5 ÷ 1

                    = 5

Now, the new length of the boat for 8 cm length of the model is given as,

New length =  Scale factor × Length of model

                   = 5 × 8

                   = 40 m.

Hence, the length of the boat is given as 40m.

Answer:

B is (2, 2)

Step-by-step explanation:

since the y is 2 for m and a, y is also 2 for b. -3 and -8 are 5 away from each other. so add 5 to -3 to get 2.

in the figure a)

y + 105 = 180 ( being linear pair )

y = 180 - 105

y = 75

Now

z = y ( being alternate angle )

z = 75

Also

x = z ( being vertically opposite angles)

x = 75

in the figure b)

we can see it is an isosceles triangle then

60 + 60 + z = 180 ( sum of angles of triangle)

120 + z = 180

z = 180 - 120

z = 60

now

y + 60 = 180( being linear pair)

y = 180 - 60

y = 120

also

x + y = 180( being co interior angles )

x + 120 = 180

x = 180 - 120

x = 60

Let's solve your equation step-by-step

-7(6+8v)=6-8v

Step 1 :Simplify both sides of the equation

-7(6+8v)=6-8v

(-7)(6)+(-7)(8v) =6+-8v(distribute)

-42+-56v=6+-8v

-56v-42=-8v+6

Step 2 : Add 8v to both sides

-56v-42+8v=-8v+6+8v

-48v-42=6

Step 3: Add 42 to both sides

-48v-42+42=6+42

-48v=48

Step 4: Divide both sides by -48

-48v/-48 =48/-48

Answer:

When a line of reflection coincides with a line of symmetry, the polygon maps onto itself. The position of the line of symmetry depends on the number of sides. For regular polygons with an even number of sides, lines of symmetry are the perpendicular bisectors of the opposite sides and the angle bisectors of opposite vertices. However, the symmetry of regular polygons with an odd number of sides does not allow lines of symmetry to connect the opposite pairs of vertices, so they have symmetry only along the perpendicular bisectors.

Given that:

Emma drinks 2/3 cups of water for every mile she hikes.

Capacity of water bottle = 4 cups

To find:

The number of miles she can hike before her water runs out.

Solution:

According to the given information,

[tex]1\text{ mile}=\dfrac{2}{3}\text{ cup}[/tex]

Multiply both sides by 3.

[tex]3\text{ miles}=2\text{ cups}[/tex]

Divide both sides by 2.

[tex]\dfrac{3}{2}\text{ miles}=1\text{ cup}[/tex]

It means, she need 1 cup water for every 3/2 miles.

Multiply both sides by 4.

[tex]\dfrac{3}{2}\times 4\text{ miles}=1\times 4\text{ cups}[/tex]

[tex]6\text{ miles}=4 \text{ cups}[/tex]

Therefore, she can hike 6 miles before her water runs out.
