From a point x = 80 feet in front of a public library, the angles of elevation to the base of the flagpole and the top of the flagpole are = 29.5° and 39° 45', respectively. The flagpole is mounted on the front of the library's roof. Find the height of the flagpole.
Let's draw the scenario to better understand the details.
To be able to determine the height of the flagpole, let's create two different triangles with 29.5° and 39° 45' angle. The two triangles have one common base at 80 Feet, yet have different heights at H+h and H respectively.
Where,
H = Height of the library
h = Height of the flag
The two triangles are proportional at a common base, thus, let's generate this expression using the Law of Sines:
[tex]\frac{H+h}{\sin(39\degree45^{\prime})}\text{ = }\frac{H}{\sin(29.5^{\circ})}[/tex]Let's simplify,

A given circle has an approximate area of 78.5 square units. How long is the circles diameter?
Remember that
The area of a circle is equal to
[tex]A=\pi\cdot r^2[/tex]we have
A=78.5 unit2
I will assume pi=3.14
substitute in the formula
[tex]\begin{gathered} 78.5=3.14\cdot r^2 \\ r^2=\frac{78.5}{3.14} \\ r=5\text{ units} \end{gathered}[/tex]the diameter is two times the radius
so
D=2(5)=10 units
therefore

-3x + 5y = -155x - 2y = -101. Find the solution2. Write an equation to replace the second equation so that the system will have infinitely many solutions.
Problem
-3x + 5y = -15
5x - 2y = -10
Solution
For this case we can solve x from the first equation and we got:
3x = 5y +15
x= (5y+15)/3
Now we can replace this value into the second equation and we got:
5((5y+15)/3) -2y = -10
25/3y +25 -2y= -10
And solving for y we got:
(25/3 -2)y =-10-25
19/3 y = -35
y= -105/19
And then we can solve for x and we got:
x= (5*(-105/19) +15)/3 = -80/19

Solve the following system of equation using substitution4x + 2y = 10?/1x - y = 13What is the solution for x?
ANSWER
x = 6
EXPLANATION
The substitution method consists on taking one equation to solve for one variable as a function of the other. Then substitute that variable with the expression we find in the other equation and then solve for that other variable.
In this case, we want to solve for x, so we'll take one of the equations and find y as a function of x. For the second equation:
[tex]\begin{gathered} x-y=13 \\ y=x-13 \end{gathered}[/tex]Now we replace y by x - 13 in the first equation:
[tex]4x+2(x-13)=10[/tex]And solve for x:
[tex]\begin{gathered} 4x+2x-2\cdot13=10 \\ 6x-26=10 \\ 6x=10+26 \\ 6x=36 \\ x=\frac{36}{6} \\ x=6 \end{gathered}[/tex]On (07.03) Choose the correct simplification of the expression b5.54. (1 point)

Explanation:
The circumference C of the circle is given by
[tex]C=2\pi r[/tex]where r is the radius.
Now we are given that C = 39 yd; therefore,
[tex]39=2\pi r[/tex]dividing both sides by 2pi gives
[tex]\frac{39}{2\pi}=\frac{2\pi r}{2\pi}[/tex][tex]r=\frac{39}{2\pi}[/tex][tex]r=6.207yd[/tex]Hence, the radius of the circle is 6.207 yards.

For the first orange box, we have that:
[tex]\begin{gathered} l=x+x=2x \\ h=2 \end{gathered}[/tex]Note that the box is divided into 2 parts.
Therefore, this perimeter is:
[tex]P_1=2(2x)+2(2)=2(2x)+4[/tex]SECOND BOX
For the second orange box, we have that:
[tex]\begin{gathered} l=x+x+x=3x \\ h=2 \end{gathered}[/tex]Note that the box is divided into 3 parts.
Therefore, the perimeter is:
[tex]P_2=2(3x)+2(2)=2(3x)+4[/tex]Using the associative property of multiplication, we have that:

The lines l, m, and n are parallel to each other and the value of x is 8.34.
What are parallel lines?Parallel lines are lines that are equidistant from each other and do not meet no matter how far they extend in either direction. Parallel lines form angles when crossed by a transversal and show some significant properties.
Angles that correspond are equal.Angles that are vertically opposite or vertically angled are equal.Interior angles that are opposite each other are equal.On the same side of the transversal, a pair of interior angles are supplementary.For the given question, we can see that lines l ║m ║n.
Therefore, (6x - 2)° = 52° [Vertically opposite angles are equal]
6x = 52 - 2
6x = 50
x = 50/6

In order to determine if the given triangles are similar, it is necessary to find the values of the missing angles.
Take into account that the sum of the interior angles of a triangle is equal to 180°, the for the missing angles you have:
180° - 90° - 46° = 44°
180° - 38° - 46° = 96°
AS YOU CAN NOTICE THE THREE ANGLES ARE NOT EQUAL.
Then, the triangles are NOT similar because it is necessary that the three angles are equal.

Answer:
[tex]\text{ \$50.75}[/tex]Explanation:
Here, we want to calculate how much Tina earns cutting lawns
From the question, she earns $8.25 per hour for 5 hours cutting lawns
What she earned in totality that week would be:
[tex]\text{ 5 }\times\text{ \$8.25 = \$41.25}[/tex]What she earned cutting lawns would be the total earned minus what she earned cutting lawns
Mathematically, we have that as:
[tex]\text{ \$92 - \$41.25 = \$50.75}[/tex]Find the slope of the line shown on the graph to the right.What is the slope of the line? The slop of the line is ___
The formula for determining slope is expressed as
slope = (y2 - y1)/(x2 - x1)
where
y1 and y2 are the y coordinates of initial and final points on the line
x1 and x2 are the x coordinates of initial and final points on the line
From the graph,
when x1 = - 4, y1 = 0
when x2 = 2, y2 = 4
slope = (4 - 0)/(2 - - 4) = 4/(2 + 4) = 4/6
Simplifying 4/6 to its lowest term
slope = 2/3
