In the given figure, BC is the Adjacent side. This is because the side is the closest side to the angle θ.
Using Trigonometry, we can also find out the measure of the ∠θ.
tan θ = opposite side / adjacent side
⇒ tan θ = 2/8 = 1/4
⇒ θ = tan^-1 (1/4)
⇒ θ = 0.245°
What is Trigonometry?The area of mathematics known as trigonometry studies how triangles' sides and angles relate to one another as well as how various angles might be used in useful ways. For determining the positions of the sun, moon, and stars, forecasting eclipses, and defining planet orbits, spherical trigonometry has been utilized for ages. To determine the distance to neighboring stars in the modern era, astronomers utilize the triangulation method. Satellite navigation systems also employ this method.By combining the laws of sines and cosines with these functions, it is possible to practically any queries concerning arbitrary triangles. When a triangle has two sides and an included angle or two angles and a side, these principles can be applied to determine the remaining angles and sides.As soon as two sides, their included angle, two angles, a side, or three sides are known, these principles can be used to calculate the remaining angles and sides of any triangle.

Step-by-step explanation:
Two airplanes are flying in the air at the same height. Airplane A is flying east at 200 mph and airplane B is flying north at 250 mph. If they are both heading to the same airport, located 30 miles east of airplane A and 40 miles north of airplane B, at what rate (in mph) is the distance between the airplanes changing?
The rate at which the distance between the airplanes is changing is;
dC/dt = 320 mi/h
We are given;
The Speed of Airplane A; dA/dt = 200 mi/h
The Speed of Airplane B; dB/dt = 250 mi/h
Aircraft A and B will form a right-angled triangle because Aircraft A is flying east and Aircraft B is flying north, and we can use Pythagoras' theorem to calculate their distance from one another.
Let C be the distance.
Therefore;
C² = A² + B²
Differentiating the above equation with respect to t,
2C(dC/dt) = 2A(dA/dt) + 2B(dB/dt)
Dividing each side of the equation by 2,
C( dC/dt ) = A( dA/dt ) + B( dB/dt )
Where dC/dt is the rate of change in distance between the two aircraft.
Now,
C² = A² + B²
C = √(A² + B²)
Substituting, A = 30 miles and B = 40 miles;
C = √(30² + 40²)
C = √( 900 + 1600 )
C = √2500
C = 50 miles
Substituting the value in the equation C( dC/dt ) = A( dA/dt ) + B( dB/dt ),
50(dC/dt) = (30 × 200) + (40 × 250)
50(dC/dt) = 6000 + 10000
50 × dC/dt = 16000
dC/dt = 16000/50
dC/dt = 320 mi/h

Find the number that should be added to the equations to make it a complete squares.
1. x^2 + 22x
2. x^2 - 2x
3. x^2 + 7x
The number that must be added to complete the squares is 121 .
Since x² represents the area of a square with a side of length x and bˣ represents the area of a rectangle with sides b and x, the process of completing the square can be seen as a visual manipulation of rectangles.
When the x² and bˣ rectangles are simply joined into a larger square, a corner is lost. The expression (b/2)² can be added to each side of the equation above to calculate the area of the remaining corner, thereby giving rise to the idiom "completing the square".the given expressions are x² + 22x
This can be written in the form of a square polynomial as :
x² + 2×x×11 + 11² = (x+11)²
Therefore we have to add 11² = 121 to the polynomial to complete the square.
Similarly for x² - 2x we have to add 1 to get the form (x-1)²
And we have to add x²+ 7x + (7/2)²
Hence the number to be added is 49/4 .

The value of the angle m∠2 = 67°.
Angle may be defined as the space between two lines. An angle consists of a vertex with which the angle is extended. When sum of two angles is exactly 90°, they are called complementary angles. For example, if we have two angles a and b then, ∠a + ∠b = 90°. When sum of two angles is exactly 180°, they are called supplementary angles. For example, if we have two angles a and b then, ∠a +∠b =180°. According to the given question ∠1 is a complement of ∠2 and we know when two angles are complementary to each other sum of their angles is 90°. So,
m∠1 + m∠2 = 90°
Now, m∠1 = 23°
23° + m∠2 = 90°
m∠2 = 90° - 23°
m∠2 = 67° which is required angle.

Determine the price of each phone and the price of each accessory.
What's the commission for each phone and the commission for each accessory?
The commission for each phone exists $2 and the commission for each accessory exists $9.
How to find the price of each phone and the price of each accessory?Given: Commission on 18 phones and 21 accessories = $204
commission on 6 phones and 14 accessories = $82.
Let the commission of each phone be P and the accessory be A.
From the given information, we get
18P + 21A = 204

Find the equation of the straight line passing through the point (3, 3)
which is perpendicular to the line
y=-}x-4
Answer:y=1/2x-41/2
Step-by-step explanation: First we have to find the slope of the line that's given, y - 4 = 2(x+2). The slope is 2 (if we multiply 2*x we would get 2x and the 2 is the slope).
Two lines are perpendicular if their slopes are negative reciprocals. So if the first line has a slope of 2, a perpendicular line would have a slope of -1/2
Now we have to find the equation for the line with slope of -1/2 that passes through the point (3,3). If we use the point-intercept form we can write it as:
y = mx + b
Since the slope is -1/2 and we know that when x = 3, y = 3 (since the line passes through that point) we can substitute the values and solve for b
y = mx+b
3 = -1/2 *3 + b
3 = -3/2 + b
3 = -11/2 + b
41/2 = b
Now we can write the equation as
y = -1/2x + 41/2
