Answer:
sin(x) = ±(√357)/29 ≈ ±0.651533
Step-by-step explanation:
The relation between sine and cosine is ...
sin(x) = ±√(1 -cos(x)^2)
sin(x) = ±√(1 -(-22/29)^2) = √(1 -484/841) = √(357/841)
sin(x) = ±(√357)/29
_____
Additional comment
The sign of the cosine is negative, which places the angle in quadrant II or III. In quadrant II, the sine is positive; in quadrant III, the sine is negative. That is, we cannot tell which sign to apply from the information given.
(20, 21, 29) is a Pythagorean triple. We suspect a typo in the question: 22 is used where 20 or 21 is likely intended.

Need help solving this linear equation
Answer: (-4, -7)
Step-by-step explanation: To solve this system of equations, we can use the substitution method.
To solve a system by substitution, we first need to isolate one of our variables. The problem is none of our variables has a coefficient of 1 or -1. In this situation, we have to look at our next best option.
In our first equation, add 2x to both sides to get
2y = -6 + 2x and just divide both sides by 2 to get y = -3 + x.
Now let's plug this value of y into our second equation.
So we have 3x + 7(-3 + x) = -61.
Simplifying from here:
3x - 21 + 7x = -61
10x - 21 = -61
10x = -40
x = -4
Since we know that x = -4, we can just plug a -4 into our equation that we created earlier to get y = -3 + (-4) or y = -7.
Since x = -4 and y = -7, our answer is the ordered pair (-4, -7).
What is the value of the missing angle?
Answer:
x=60°
Step-by-step explanation:
The Sum of all sides of a pentagon is 540°
And in the figure there are 2 sides with 150° and 90°
Now we have,
[tex]90+90+150+150+x=540\\\\480+x=540\\\\x=540-480\\\\x=60[/tex]

You continue your journey of riding ferris wheels and decide to ride the largest ferris wheel in the world: The High Roller in Las Vegas, Nevada! The High Roller is 550 feet tall with a diameter of 520 feet and the platform making the remaining 30 feet. Your friend who really does not like heights waits for you to get off the High Roller while standing 450 feet away from you, horizontally.

If you are currently 326 feet in the air, what is the angle of depression from you to your friend?
The angle of depression from you to your friend is 54.1°
Trigonometric ratios
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let θ represent the angle between me in air and my friend, hence:
tanθ = 326 / 450
θ = 35.9 degrees
The angle of depression = 90 - 35.9 = 54.1°
The angle of depression from you to your friend is 54.1°

The question is in the picture.
Answer:
x = 7[tex]\sqrt{3}[/tex]
Triangle area formula: base * height * 1/2
We are given:
Base - 14 cm
Height - x
Using the pythagorean theroem (a^2 + b^2 = c^2) we can figure out the height.
We are given:
Side a - 14 / 2 = 7 cm
Side b - the height (x)
Side c - 14 (it's an equilateral triangle)
Now, substitute the given values:
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 = 147
x = [tex]\sqrt{147}[/tex]
x = 7[tex]\sqrt{3}[/tex]

In a recent year, 28% of all college students were enrolled part-time. If 7.2 million college students were enrolled part-time that year, what was the total number of college students? Round your answer to the nearest million.
Answer:
26 million
Step-by-step explanation:
x = total number in million
28% * x = 7.2
so x = 7.2/0.28 = 25.7 ≈ 26
What is the slope of the line represented by this equation?
-3x + 8y = 12
Step-by-step explanation:
Turn the equation into a slope-intercept form equation:
[tex]8y=3x+12[/tex]
Divide each side by 8 to simplify y:
[tex]y=\frac{3}{8} x+1.5[/tex]
The slope is 3/8.
Using the format:
[tex]y=mx+b[/tex]
3/8 is in place of m, the slope.
