A 100 foot wire is extended from the
ground to the top of a 60 foot pole,
which perpendicular to ground level.
Find, to the nearest degree, the
measure of the angle that the wire
makes with the ground.
The angle that the wire makes with the ground is 36.87° with horizontal.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
The given situation is making a right-angle triangle,
By Pythagoras' theorem in the triangle.
Base = √(100² - 60²) = 80 foot
By tan trigonometric function,
tanx = 60/80
x = 36.87°
Hence "The wire's angle with the ground is 36.87° with respect to the horizontal".

y=x²+2x+2
First, we should try to change the last number in a way so we can factor the entire thing
y=x² + 2 x + 1
tooo make it look like y=(x + 1 )²
the only difference between the original y=x² + 2x + 2
and the factor-able y=x² + 2x + 1 is simply changing the
2 to a 1 (Since we can't randomly change the 2 to a 1, we can add 1 and subtract a 1 to the equation at the same time to keep it balanced.)

The side of a regular pentagonal pyramid is 6 feet long. The slant
height of the is 7 feet long. What is the lateral area of the pyramid.
Answer:
105 sq ft.
Step-by-step explanation:
LA = slant height time perimeter of the base divided by 2.
Perimeter = 5(6) = 30
LA = 7(30)/2 = 105 sq ft.
PLEASE HELP!! What do most marketing entrepreneurs do to prepare to launch their
businesses? (this is actually business not math but)
Marketing entrepreneurs choose a marketing niche first to prepare to launch their business. Thus, option B is correct.
What is marketing niche?The portion of a market that a particular product is targeted toward is called a niche market. The product's market niche determines its price range, level of production, target demographics, and feature set that is intended to address a particular market need. Additionally, it is a small market sector. A product or service may occasionally be created specifically to meet the needs of a niche market.
Not all products can be classified by their market niche. The highly specialised niche market competes against numerous super companies and strives to remain viable. Even well-known companies develop products for specific markets; Hewlett-Packard produces separate machines in addition to all-in-one printing, scanning, and faxing units that are aimed at the home office market.

Given: EL≅KP Prove: KE≅LP
Answer:
See Below.
Step-by-step explanation:
We are given that:
[tex]EL\cong KP[/tex]
And we want to prove that:
[tex]KE\cong LP[/tex]
Congruent chords have congruent arcs. Therefore:
[tex]\stackrel{\frown}{EL}\, \cong \, \stackrel{\frown}{KP}[/tex]
Arc EL is the sum of Arcs LP and PE:
[tex]\stackrel{\frown}{EL}\,=\, \stackrel{\frown}{LP}+\stackrel{\frown}{PE}[/tex]
Likewise, Arc KP is the sum of Arcs KE and PE:
[tex]\stackrel{\frown}{KP}\, =\, \stackrel{\frown}{KE}+\stackrel{\frown}{PE}[/tex]
Since Arcs EL and KP are congruent:
[tex]\stackrel{\frown}{LP}+\stackrel{\frown}{PE}\, =\, \stackrel{\frown}{KE}+\stackrel{\frown}{PE}[/tex]
Subtraction Property of Equality:
[tex]\stackrel{\frown}{LP} \, \cong\, \stackrel{\frown}{KE}[/tex]
Congruent arcs have congruent chords. Therefore:
[tex]LP\cong KE[/tex]
Does anyone know the answer to this?!
Answer:
65°
Step-by-step explanation:
Properties of a triangle:
Triangles always have 3 sidesThe sum of the interior angles of a triangle must be equal to 180°.To solve:
Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:a + b + c = 180(The variables can be assigned to any value in this situation)Since two angles are already given, replace 2 variables:a + 85 + 30 = 180Solve the equation by subtracting on both sides:a = 65The value of a is the measure of the missing angle. The problem is solved.Answer:
the missing angle is 65
Step-by-step explanation:
a whole triangle is 180
subtract the given angles from 180
180
- 85
----------
95
subtract the remaining angle

You have 3 red marbles, 5 green, and 2 blue marbles. What is the probability of pulling a blue marble and then replacing the first marble and then grabbing a green marble?
(As a percent)
Answer:
I think it's [tex]\frac{7}{10}[/tex].
Why 7/10?
Well, the probability of pulling out a blue marble + pulling out a green marble is also written as [tex]\frac{2}{10} +\frac{5}{10}=\frac{7}{10}[/tex]

A graph of a system of two equations is shown. PLEASE HELP!!!!!
Answer:
(-4.5, 1.5)
Step-by-step explanation:
solve the system by substitution 3x-y=10 2x=y
Answer
X=10 and y=20
Step-by-step explanation:
since y=2x, you need to substitute that into the equation to get:
3x-(2x)=10
And evaluate:
x=10
Then substitute 10 into the equation: 2x=y:
2(10)=y
evaluate:
20=y
Now go back to the original equation to check your answer and substitute the values in:
3(10)-(20)=10
30-20=10
10=10
Simplify:

What is the equation of the hyperbola?[tex]\frac{x^{2} }{a^2}+\frac{y^2}{b^2} =1[/tex]
Compare the above equation of the hyperbola with given equation
therefore a=2
vertices are (-a,0) and (a,0)
Therefore the vertices are (-2,0) and (2,0)
