Answer: 30 degrees

Step-by-step explanation:

Assuming this is a three sided polygon, this would make it a triangle. Interior angles of a triangle sum to 180 degrees. 85+65+u=180

150 + u = 180

U = 30 degrees

Answer:

A

Step-by-step explanation:

Its a right angle, so you have to use trigonometry.

To find x , you use sin60° = opposite/hypotenuse

opposite = x and hypotenuse = 5 . So,

sin60°= x/ 5

5sin60° = x

put the value into your calculator you ' ll get:

[tex] x = \frac{5 \sqrt{3} }{2} [/tex]

To find y, cos60°= adjacent/hypotenuse

adjacent= y and hypotenuse = 5. So,

cos60°= y/5

5cos60°=y

[tex]y = \frac{5}{2} [/tex]

The amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed.

The surface area of rectangular prism can be given as,

[tex]SA=2(wl+hl+hw)[/tex]

Here, (w) is the width, (h) is the height and (l) is the length of the prism.

Becca is painting a birdhouse. The shape of the birdhouse is similar to rectangular prism with dimensions as, height of 13cm, a width of 5 cm, and a length of 8cm.

Now Becca wants to paint this house using 1 coat. As this paint has to be cover each surface of the house. Thus the amount of total paint should be equal to the surface area of the house.

Here, the dimensions of house is as, height of 13cm, a width of 5 cm, and a length of 8cm. Therefore the surface area of it is,

[tex]SA=2(5\times8+13\times8+13\times5)\\SA=418\rm cm^2[/tex]

Hence, the amount of paint which will Becca need to paint the birdhouse in 1 coat is 418 cm².

Answer:B

Step-by-step explanation:

For [K] > 0, the dilated image will be larger than the original image.

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle ABC which is taken to triangle A'B'C' by a dilation.

After dilation by scale factor [K], the length of the sides of triangles change by the following rule -

A'B' = K(AB)

B'C' = K(BC)

C'A' = K(CA)

If K < 0, the image will shrink. If K > 0, the image will enlarge

Therefore, for [K] > 0, the dilated image will be larger than the orginal image.

Answer:

Step-by-step explanation:

The vertex is halfway between focus and directrix, at (0,0).

The equation has the form y = ax².

Focal length p = distance between focus and vertex = 1

p = 1/|4a|

1 = 1/|4a|

|a| = ¼

The focus lies below the vertex, so the parabola opens downwards and a<0.

y = -¼x²

Equation represents a parabola with the focus at (0, -1) and

the directrix y=1 is [tex]x^2=-4y[/tex]

Given :

a parabola with the focus at (0, -1) and the directrix y= 1

The standard equation of parabola is  [tex]y-k=\frac{1}{4p} (x-h)^2[/tex]

Focus is at (0,-1)

The midpoint of focus and directrix is the vertex

Directrix is at y=1

Midpoint of (0,-1)  and y=1 is (0,0)

So the vertex is (0,0) that is our (h,k)

Now we find the value of p

The distance between vertex (0,0)  and focus (0,-1) is the value of p

focus  and vertex are 1 unit away. So p=-1

we got h=0 and k=0 and p=-1

Replace all the value in the standard equation

[tex]y-0=\frac{1}{4(-1)} (x-0)^2\\y=\frac{-1}{4} x^2\\4y=-x^2\\x^2=-4y[/tex]

Equation represents a parabola with the focus at (0, -1) and

the directrix y=1 is [tex]x^2=-4y[/tex]

Simplify the expression.

Answer:

The numbers are 13 , 16

Step-by-step explanation:

First number be x

Second number be y

x - y = -3 --------------------(I)

x = -3 +y

8x + 5y = 184  ---------------(II)

substitute x = -3 + y in equation(I)

8*(-3 + y) + 5y = 184

-24 + 8y + 5y = 184

-24 + 13y = 184

         13y = 184 + 24

         13y = 208

            y = 208/13

y = 16

Plugin y = 16 in (I)

x - 16 = -3

      x = -3 +16

    x = 13

The inequality shown in the option D, 6 < x + 3 < 9 has the given solution set.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

A number line is a straight line which is drawn horizontally where numbers are placed in an equal intervals.

Given a number line where the interval from 3 to the number 6 is marked.

But 3 and 6 is not included since it is an open circle there.

So the inequality represented in the number line is 3 < x < 6.

We have to find the inequality in the option which is equivalent to 3 < x < 6.

Consider 6 < x + 3 < 9

Subtracting throughout the inequality with 3, we get,

6 - 3 < x + 3 - 3 < 9 - 3

3 < x < 6.

Hence the inequality represented in option D has the solution represented in the number line.
