[tex](A)\frac 1 {cosx} \frac 1 {sin x} - \frac {cosx} {sin x} = \frac {sin x} {cosx} \\\\(B)\frac{1-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(C) \frac{(sin^2x + cos^2x)-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(D) \frac{sin^2x }{cos x sin x} = \frac {sin x} {cosx}\\\\(E)\frac {sin x}{cos x} = \frac {sin x}{cos x}[/tex]
In step A, you replace all trigonometric functions with their definitions in terms of sine and cosine.
In step B, you add the two together as you add fractions.
In step C, you replace 1 with the sum of the squares of sine and cosine.
In step D, you add the cosine terms together so they disappear.
In step E, finally, you divide numerator and denominator by [tex]sin x[/tex].
Graph each equation. Determine the solution of the system of equations.

Can the side lengths of 3, 10, and 13 form a triangle?- quoara
Answer:
No, it can not.
Step-by-step explanation:
For a triangle to exist. The two sides of length of every triangle added up must be greater than the other length.
Here,
13 + 3 > 10
13 + 10 > 3
but,
3 + 10 > 13 is false
so, the side lengths 3, 10, 13 can not form a triangle.

Answer:
x = 3
Step-by-step explanation:
When chords intersect inside a circle, the product of the lengths of the two segments of one chord equals the same product of the other chord.
10x = 5 × 6
10x = 30
x = 30/10
x = 3
Find the value of x.
Step-by-step explanation:

The angle formed by a tangent on a circle with a radius is always 90 degrees thus the measure of x for the given circle and tangents is 18.
What is a tangent of a circle?The tangent of a circle is a line that intersects the circle at the periphery of the circle.
If you draw a line that goes through the center to the tangent touching point then it will give you a 90-degree angle.
As per the given circle and two tangents.
Since The angle formed by a tangent on a circle with a radius is always 90°.
Therefore, the sum of the other two angles 3x and 126° will be 180°.
3x + 126 = 180
3x = 54
x = 18
Hence "The angle formed by a tangent on a circle with a radius is always 90 degrees thus the measure of x for the given circle and tangents is 18".

How many sides does a convex polygon have if the sum of measures of its angles is 2 520deg?
Answer:
16 sides
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here sum = 2520° , then
180° (n - 2) = 2520° ( divide both sides by 180° )
n - 2 = 14 ( add 2 to both sides )
n = 16
the polygon has 16 sides

Does anyone know how to do this?
Answer:
y = - 3x - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 10 - 3x = - 3x + 10 ← is in slope- intercept form
with slope m = - 3
y = - 6x - 4 ← is in slope- intercept form
with y- intercept c = - 4
then equation of required line is
y = - 3x - 4
Hello!
The slope of the first line is -3.
The y-intercept of the second line is -4.
How did I identify the slope & y-intercept?
Let me share my "secret"
Well, both equations are written in slope-intercept form (y=mx+b)
where m = slope & b = y-intercept.
Now you know ;-)
Anyway, the new line should have the same slope as the first line (-3)
And the y-intercept of the second line is -4.
So the equation is
y=-3x-4
Hope everything's clear!

Right angle triangle:
A right angle triangle has one of its angles as 90 degrees. The sides can be found using Pythagoras theorem.
The side of the base triangle can be found using Pythagoras theorem.
c² = a² + b²
c² = 9.2² + 5.8²
c² = 84.64 + 33.64
c = 10.9 ft
using similar triangle ratio,
5.8 / 10.9 = 10.9 / x + 5.8
5.8x = 118.81 - 33.64
x = 85.17 / 5.8
x = 14.6844827586
x = 14.7 ft
The height of the tree to the nearest foot is 14.7 + 5.8 = 20.5 ft

d. Range: all numbers from 0 to 60.
Answer:
a.) Domain: all numbers from 0 to 170 and d. Range: all numbers from 0 to 60
Step-by-step explanation:
The domain is all of the numbers that the graph is on, over the x-axis. Looking at the x-axis, the graph only spans across 0-170, so the answer would be a.) Domain: all numbers from 0 to 170.
The range is all of the numbers that the graph is on, over the y-axis. Looking at the y-axis, the graph only spans across 0-60, so the answer would be d. Range: all numbers from 0 to 60.

Using the Pythagorean Identity find the cos(0) if the sin(0) =20/29 given that the terminal side is in the 2nd
quadrant. You must show all work.
The value of cosθ from the trigonometric identity is equal to -21/29
Data;
sin(0) = 20/29quadrant = 2nd quadrantPythagorean TheoremThis formula is used to find the missing side of a right angle triangle.
This is given as
[tex]hypothenuse^2 = adjacent^2 + opposite^2[/tex]
But in trigonometric ratio, the sine ratio is
[tex]sin \theta = \frac{opposite}{hypothenuse}[/tex]
This implies that
opposite = 20hypothenuse = 29adjacent = ?Let's find the adjacent using Pythagorean theorem
[tex]x^2 = y^2 + z^2\\29^2 = 20^2 + z^2 \\z^2 = 29^2 - 20^2\\z^2 = 441\\z = \sqrt{441} \\z= 21[/tex]
Now that we know the value of adjacent,
The value of cos(0) will be
[tex]cos \theta = \frac{adjacent}{hypothenuse} \\cos \theta =- \frac{21}{29}\\[/tex]
Note: The negative sign in front of the ratio indicates the fact that in the second quadrant, only sine theta is positive, the rest are negative.
The value of cosθ is equal to -21/29
