The equation of the line that passes through the points (2,1) and (6,-5) is y = -3/2x + 4. This is calculated using the formula for a line y - y1 = m(x - x1) and the formula for slope.
In order to find the equation of the line passing through the points (2,1) and (6,-5), we can use the formula for a line y - y1 = m(x - x1). Here, m is the slope of the line. We can calculate the slope using the formula (y2 - y1) / (x2 - x1). Thus, for the points (2,1) and (6,-5), the slope m is (-5 - 1) / (6 - 2) = -6/4 = -3/2. We can substitute one pair of points and the slope into the line equation. Let's use (2,1). The equation of this line is then y - 1 = -3/2 * (x - 2). Simplifying, we get the equation of the line to be y = -3/2x + 4.

The measure of DE of the triangle is given by law of sines and DE = 31.3
The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.
Law of Sines :
a / sin A = b / sin B = c / sin C
Given data ,
Let the triangle be represented as ΔDEF
Now , the measure of sides of the triangle are
The measure of EF = 22
The measure of angle ∠D = 43°
The measure of ∠E = 62°
And , the measure of ∠F = 180° - 43° - 62° = 75°
From the laws of sines , we get
a / sin A = b / sin B
On simplifying , we get
EF / sin 43° = ED / sin 62°
So , the measure of DE = ( 22 / 0.7 ) ( sin 75° )
And , the measure of DE = 31.3 units
Hence , the measure of DE of triangle is 31.3 units

Answer:
4/5 forms a proportion with 16/20.
Step-by-step explanation:
We are given an rational number as 16/20.
we have to find another rational number which is equivalent to it.
as both 16 and 20 are multiple of 4 we could also represent the ratio 16/20 as:
we cancel 4 on both the numerator and denominator to get .
Hence, the ratio is proportion with .
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides.
The triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.
How to find the type of triangle?
By the Pythagoras theorem we know that the if the square of the longest side of the triangle is equal to the sum of the square of other two sides. Thus,
By this law it is observed that,
The sides of the given triangle are 3.8 cm ,3.7 cm, and 5 cm.
Here the longest side is 5 cm. Thus check the type of triangle using above formula. Longest side,
Other two sides,
Therefore,
Hence the triangle formed by the sides 3.8 cm ,3.7 cm, and 5 cm is acute angle triangle.

The distance between the two skyscrapers is 1269ft
I've added as an attachment, a figure that illustrates the scenario
First, we calculate distance AB using the following tangent ratio
So, we have:
Make AB the subject
Next, we calculate distance AC using the following tangent ratio
So, we have:
Make AB + BC, the subject
Make BC the subject
Substitute
Hence, the distance between the two skyscrapers is 1269ft
