Answer:

x=33, y = 38 and z = 109 degrees

Step-by-step explanation:

x = 33 degrees ( internal alternate angles)

y = 180 - 33 - 109) = 38 degrees ( 180 degrees in a triangle)

z = 109 degrees ( opposite angles of a parallelogram are equal)

Two figures are shown. EFJL is dialation of ABIK AB has a length of 12 and EF has a length of 3

Dimas [21]

The scale factor of dilation from AB to EF is 0.25

<h3>How to determine the scale factor of dilation?</h3>

The given parameters are:

EFJL is dilation of ABIK
AB has a length of 12
EF has a length of 3

From the above parameters, side lengths AB and EF are corresponding sides

This means that:

The scale factor of dilation (k) is

k = AB/EF

So, we have

k = 3/12

Evaluate

k = 0.25

Hence, the scale factor of dilation from AB to EF is 0.25

Scorpion4ik [409]

Given:

In an isosceles triangle,

One base angle = (4x-15)°

Vertex angle = 95°

To find:

The value of x.

Solution:

Let the triangle be ABC.

We have,

$m\angle A=95^\circ$

$m\angle C=(4x-15)^\circ$

Since ABC is an isosceles triangle and AB=AC, therefore, the base angles are equal.

$m\angle B=m\angle C=(4x-15)^\circ$

Using angle sum property of triangles, we get

$m\angle A+m\angle B+\angle C=180^\circ$

$95^\circ+(4x-15)^\circ+(4x-15)^\circ=180^\circ$

$(8x+65)^\circ=180^\circ$

$(8x+65)=180$

On further simplification, we get

$8x=180-65$

$8x=115$

$x=\dfrac{115}{8}$

$x=14.375$

Therefore, the value of x is 14.375.

Choose a fraction that makes the following sentence true. 0.1 is a rational number because it can be written as ___.

pychu [463]

Answer: Option 'a' is correct.

Step-by-step explanation:

Since we have given that

0.1 is a rational number because it can be written as $\dfrac{p}{q}$ form.

So, we can write it as

$0.1=\dfrac{0.1}{1}\\\\=\dfrac{0.1\times 10}{1\times 10}\\\\=\dfrac{1}{10}$

so, it can be written as $\dfrac{1}{10}$

Hence, option 'a' is correct.
