Zane and his favorite geometry student, , have just set sail for a day of fun on lake Erie. A spring squall quickly forms and catches you off guard, leaving you adrift on the lake. Zane suddenly discovers he has an irrational fear of water and is reduced to hugging the mast. You hear Sherman barking from the top of a lighthouse to help guide you to shore. In order to save Zane and yourself, you must calculate how far away you are from this lighthouse. Using a range finder, you expertly measure the distance from the sailboat to the top of the lighthouse at 350 yards.
angle B is 40 degrees.
(a) Based on the above information, find the distance across the water from the sailboat to the island
where the lighthouse is standing. You can only use trigonometry to solve. You must show all work for
credit. Round your answer to the nearest whole number if needed.
(b)Calculate the height of the lighthouse. You can only use trigonometry or Pythagorean Theorem to
solve.
Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.
_________________________________________________________
According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).
Θ = 40hyoptenuse = 350adjacent = xcosine40 = x/350
[multiply both sides by 350]
350 · cosine40 = x
[put calculator in degree mode]
x ≈ 268 yards
So, the distance across the water from sailboat to the island is 268 yards.
_________________________________________________________
Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).
a^2 + b^2 = c^2
a = ? (opposite or height)b = 268 (adjacent)c = 350 (hypotenuse)a^2 + (268)^2 = (350)^2
a^2 + 71824 = 122500
a^2 = 122500 - 71824
a^2 = 50676
[square both sides]
[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]
a = [tex]\sqrt{50676}[/tex]
a ≈ 225
So, the height, opposite, of the lighthouse is 225 yards.

1. Students who attended a track and field meet were polled, and 75% of them said that track and field meets are more fun to attend than soccer games. Answer the following:
Part 1: Is it a valid conclusion to say that track and field sports are more popular than soccer based on tha survey? Explain your response.
Part 2: What is a better method of determining which sport is more popular? Explain why.
help plz :3 im new and don't know how this works so 15 points I think
Answer:
Part 1: It is not a valid conclusion to say that track and field sports are more popular than soccer based on the survey. The survey was taken at a track and field event so the people that were surveyed are probably biased.
Part 2: A better way of determining which sport is more popular is by counting how many people show up to each event and comparing the results.

Explain the relationship between the shape of the base of a prism and the number of lateral faces. Use examples to justify your answer.
Answer:
A prism is a three-dimensional solid figure with two parallel faces, called bases, that are congruent polygons, and lateral flat faces which are rectangles in a right prism, and are parallelograms in an oblique prism.
Sample response: A triangular prism has a 3-sided base and 3 lateral faces. A rectangular prism has a 4-sided base and 4 lateral faces. The number of sides of the base of a prism is equal to the number of lateral faces of the prism.

A linear function that represents the number of video games purchased at an electronics store is compared to a different linear function that represents the amount of money the store made that day. Describe the key features of the functions that are needed to determine if these lines intersect
Answer:
The key features needed to determine if these two linear functions intersect would be their y-intercept and their slopes. We need this information because it would allow us to graph these two linear functions, and if we can graph them, we can see if these lines intersect.

(Please mark Brainliest)
Does anybody know the right answer?
Given:
A line passes through the points (9,9) and [tex](x_2,-1)[/tex].
The slope of the line is [tex]\dfrac{5}{6}[/tex].
To find:
The value of [tex]x_2][/tex].
Solution:
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The line passes through the points (9,9) and [tex](x_2,-1)[/tex]. So, the slope of the line is:
[tex]m=\dfrac{-1-9}{x_2-9}[/tex]
[tex]m=\dfrac{-10}{x_2-9}[/tex]
It is given that the slope of the line is [tex]\dfrac{5}{6}[/tex].
[tex]\dfrac{5}{6}=\dfrac{-10}{x_2-9}[/tex]
[tex]5(x_2-9)=-10(6)[/tex]
[tex]5x_2-45=-60[/tex]
[tex]5x_2=-60+45[/tex]
[tex]5x_2=-15[/tex]
Divide both sides by 5.
[tex]x_2=-\dfrac{15}{5}[/tex]
[tex]x_2=-3[/tex]
Therefore, the value of [tex]x_2[/tex] is [tex]-3[/tex].
The central angle of arc ST is 70 degrees. What is the measure of an inscribed
angle whose endpoints are points S and T?
Answer:
35
Step-by-step explanation:
The measure of an inscribed angle whose endpoints are points S and T will be 35°.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
The central angle of arc ST is 70°.
The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have
Inscribed angle = 70° / 2
Inscribed angle = 35°
The measure of an inscribed angle whose endpoints are points S and T will be 35°.

Given the vertices (1, 5) and (11, 15) for the corners labeled with red stars, the diagonal of the square C will be the length of the line joining the two vertices.
Using the Distance Formula:
Since 1 Square Unit = 25 Square Feet
1 Unit =5 feet
Therefore, the length of the diagonal

Answer:
64 degrees.
Step-by-step explanation:
We are given that angle QRP is 32 degrees.
We are also given that angle PRS is 84 degrees.
Add those two angles to get the measure of angle QRS.
measure of angle QRS= 116 degrees.
Same-side interior angles are supplementary
So,
116+ angle PQR= 180
subtract both sides by 116.
PQR=64
Therefore the measure of angle PQR is 64 degrees.

HELP!!! Find the measure of each angle.
Answer:
Step-by-step explanation:
This figure is called a cyclic quadrilateral. The vertices of all sides lie on a circle.
That's property one.
Property 2 is that the opposite angles add to 180 degrees.
6y - 4 + 5y - 3 = 180 is the y angles. Combine like terms.
11y - 7 = 180 Add 7 to both sides.
11y - 7 + 7 = 180 + 7
11y = 187 Divide by 11
y = 187/11
y = 17
H = 17 * 6 - 4
H = 102 - 4
H = 98
F = 5y - 3
F = 5*17 - 3
F = 85 - 3
F = 82
=====================
11x + 8 + 8x + 1 = 180
19x + 9 = 180
19x = 171
x = 171/19
x = 9
E = 9*11 + 8
E = 99+8
E = 107
G = 8*9 + 1
G = 72 + 1
G = 73

Answer:
Centre = (2, -3)
radius = 5units
Step-by-step explanation:
The standard form of a circle is expressed as;
x²+y²+2gx+2fy+c = 0
Centre = (-g, -f)
radius r = √g²+f²-c
Given the equation;
x²+y²-4x+6y-12 = 0
Compare
2gx = -4x
2g = -4
g = -2
Similarly;
2fy = 6y
2f = 6
f = 3
Centre = (-(-2), -3)
Centre = (2, -3)
Radius = r = √(-2)²+3²+12
r = √4+9+12
r = √25
r = 5 units
