Answer:

x = 15.9

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj / hyp

cos 28 = 14/x

x  cos 28 = 14

x = 14 / cos 28

x=15.85598

Rounding to the nearest tenth

x = 15.9

Right or wrong ????
tangare [24]

Answer:

c   1/2

Step-by-step explanation:

You are incorrect.

We are going from ABCDEFGH to A'B'C'D'E'F'G'H'. We are going from the large octagon to the small octagon. The scale factor of a dilation is the number you multiply the original lengths to get the lengths of the dilation.

scale~factor = \dfrac{length~of~dimension~in~dilated~image}{length~of~corresponding~dimension~in~original~figure}

Look at point (6, 0) which becomes (3, 0) in the dilation.

The distance from the origin to (6, 0) is 6 units.

The distance from the origin to (3, 0) is 3 units.

scale factor = dilated/original = 3/6 = 1/2

The scale factor of the dilation is 1/2.

Also look at segment AB whose length is 4. The length of segment A'B' is 2.

scale factor = dilated/original = 2/4 = 1/2

Answer: 1/2

Use the Pythagorean theorem to obtain the function​ D(x) for the length of the diagonal of a double square of width x.
Yuri [45]

Answer:

D(x)= x\sqrt{2}

Step-by-step explanation:

Given

Side = x

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

D^2= Side^2 + Side^2

Substitute x for Side

D^2= x^2 + x^2

D^2= 2x^2

Take the square root of both sides

D= \sqrt{2x^2

Split

D= \sqrt{2} * \sqrt{x^2

D= \sqrt{2} * x

D= x\sqrt{2}

Express as a function.

D(x)= x\sqrt{2}
