Given that ABCD is a rhombus, what is the value of x?
A. 18.25
B. 20.75
C. 30 O
D. 64
E. 86
F. Cannot be determined
Answers
Answer: 20.75
Step-by-step explanation:
X+(3x+7)+90=180
-90 on both sides
X+(3x+7)=83
-7 on both sides, add x’s
4x=83
Divide by 4 on both sides
X=20.75
The required measure of the value of x in the rhombus is 20.75.
What are angles?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
A fire of rhombus is shown,
Where the diagonal of the rhombus bisect each other at 90°.
let's assume the point at the intersection, is o.
Now, In triangle AOD the sum of the interior angle should be 180°,
x + 90 + 3x + 7 = 180
4x = 180 - 90 - 7
4x = 83
x = 20.75°
Thus. the required measure of the value of x in the rhombus is 20.75.

Two radar stations reconnoiter a plane at the same time. The angles
of elevation to the plane are 20° and 59º. How far apart are the two
radar stations if the plane is at an altitude of 30 km?
km (round to two decimal places)
20
59
30 km
Enter the answer
Answers
Answer:
The distance apart of the two planes is either 100.45 km or 64.40 km
Step-by-step explanation:
The given parameters are;
The angle of elevation of the plane from the two radar stations are; 20° and 59°
The altitude of the plane = 30 km
The horizontal distance from each of the radar stations from the plane is given as follows;
[tex]tan(\theta) = \dfrac{Altitude \ of \ the \ plane}{The \ horizontal \ distance \ of \ radar \ station \ from \ the \ plane}[/tex]
Therefore, we have;
[tex]The \ horizontal \ distance \ of \ radar \ station \ from \ the \ plane = \dfrac{Altitude \ of \ the \ plane}{tan(\theta)}[/tex]For each of the given radar stations, and their elevations, we have;
[tex]The \ horizontal \ distance \ of \ the \ 1st \ radar \ station \ from \ the \ plane = \dfrac{30 \ km}{tan(20^{\circ})}[/tex]
[tex]The \ horizontal \ distance \ of \ the \ 2nd \ radar \ station \ from \ the \ plane = \dfrac{30 \ km}{tan(59^{\circ})}[/tex]
The distance between the two radar stations, d = The sum of their horizontal distances from the plane
Therefore;
[tex]d = \dfrac{30 \ km}{tan(20^{\circ})} + \dfrac{30 \ km}{tan(59^{\circ})} \approx 100.45 \ km[/tex]
However, when the radar stations are on the same side, we have;
The distance between the two radar stations, dₓ = The difference of their horizontal distances from the plane
[tex]d_x = \dfrac{30 \ km}{tan(20^{\circ})} - \dfrac{30 \ km}{tan(59^{\circ})} \approx 64.40 \ km[/tex]
The distance apart of the two planes is either 100.45 km or 64.40 km
Which are examples of non-visible light?
A) radio waves and ultraviolet light

C) white light from a lightbulb and rainbows
D) white light from the sun and microwaves
Answers
The answer to your question which are examples of non-visible light is A:radio waves and ultraviolet light
All the options given from option A to D are all electromagnetic waves since light is an electromagnetic wave.
Option A consists of radio waves and ultraviolet waves which are both non-visible light.Option B consists of rainbows and X-rays. Although, X-rays are non-visible light, rainbows are visible. So, option B is not correct.Option C consists of white light from a light bulb and rainbows. Both white light from a light bulb and rainbows are both visible light. So, option C is not correct.Option D consists of white light from the sun and microwaves. Although, microwaves are non-visible light, white light from the sun is visible. So, option C is not correct.Since both options in option A are both non-visible light,

A pattern exists in the sum of the interior angles of polygons. The sum of the interior angles of a
triangle is 180°, of a quadrilateral is 360°, and of a pentagon (5 sides) is 540°. What is the sum of
the interior angles of a nonagon (9- sided shape)?
Answers
Answer:
1,620 degrees.
Step-by-step explanation:
It has a steady pattern. 180 x 2 = 360, which is quadrilateral. 180 x 3 = 540, which is a pentagon. so, 180 x 9 = 1,620
Angelica needs 1.25 pounds of beef to make 4 person tacos. How many pounds of beef will she need to feed 10 people?
Answers
Answer:
3.125 pounds of beef
Step-by-step explanation:
Set up a proportion where x is the number of pounds of beef needed to feed 10 people:
[tex]\frac{1.25}{4}[/tex] = [tex]\frac{x}{10}[/tex]
Cross multiply and solve for x:
12.5 = 4x
3.125 = x
So, to feed 10 people, she will need 3.125 pounds of beef

Answers
Given:
A polynomial has a root of −2.
To find:
The factor that will divide evenly into the polynomial.
Solution:
We know that, if c is a root of a polynomial P(x), then (x-c) is a factor of polynomial P(x).
we have,
-2 is a root of polynomial.
⇒ (x-(-2)) is a factor of polynomial.
⇒ (x+2) is a factor of polynomial.
⇒ (x+2) will divide the polynomial completely.
Therefore, the factor (x+2) will divide evenly into the polynomial.
The factors of a polynomial divide the polynomial evenly, without remainder
The factor of the polynomial is x + 2
The root of the polynomial is given as:
[tex]\mathbf{Root = -2}[/tex]
Assume the polynomial is a function of x.
i.e. the variable of the polynomial is x
Then the root can be represented as:
[tex]\mathbf{x= -2}[/tex]
Add 2 to both sides
[tex]\mathbf{x + 2= -2 +2}[/tex]
So, we have:
[tex]\mathbf{x + 2= 0}[/tex]
Hence, the factor of the polynomial is x + 2

Exponents
By Vicki Young
I open up my textbook when I first get out of bed,
Start studying those rules, just like my teacher said!
Recognizing bases, exponents, too.
Exponents must be positive, negatives won't do.
I've got to work these problems, I've got to find a way.
Oh, I feel frantic today!
I start to see a pattern to how these things are done.
I raise to zero power and the answer's always one.
The base just can't be zero - I must remember that.
Just three more rules to learn now and then I can relax.
I'll put it all together, I'll know it pretty soon.
Oh, I feel better at noon!
To multiply same bases, exponents I combine.
Dividing's just the opposite, but then I must decide
To subtract the smaller power, the base correctly place.
The power rule says multiply, parentheses erase.
I know I've got these rules now, I know I've got them right.
Oh, I feel lucky tonight!

What are mathematical operations?An operation is a mathematical function that transforms zero or more discrete input values into discrete output values. The complexity of the operation depends on how many operands there are. The rules that specify the order in which specific operations should be carried out in order to solve an expression are referred to as the order of operations. Parentheses, exponents, multiplication, division (from left to right), addition, and subtraction are the order of operations. (Left to Right) PEMDAS (from left to right).So, −112−(+312)−(−58):
