sin x = sqrt(3)/2
Answer:
Step-by-step explanation:
We are given that
We have to find all solutions of the given equation
We know that
sin x is positive then the value of sin x will lie in I quadrant and II quadrant.The value of sin x is negative in III and IV quadrant .
We are given that sin x is positive then the solution will lie in I and II quadrant only.Therefore, the solution of sin x will not lie in III and IV quadrant .
...(I equation )and ...(II equation)
In II quadrant change into
Cancel sin on both side of equation I
Then, we get
...(II equation )
Cancel sin on both side of equation II
Then we get
Hence, the solutions of equation are
The solutions of the equation are:
x = 60 degrees
x = 120 degrees
x = 420 degrees
x = 480 degrees, and so on.
We have,
The solutions to the equation sin(x) = √3/2 are any angles where the sine of the angle is equal to √3/2.
So,
sin 60 = √3/2
sin 120 = sin (π - 60) = sin 60 = √3/2
In trigonometry 180 is written as π.
Since (π - 60) is in the secondquadrant sin 60 is positive.
sin 420 = sin (360 + 60) = sin 60 = √3/2
In trigonometry 360 is written as 2π.
Since (2π + 60) is in the Firstquadrant sin 60 is positive.
Similarly,
sin 480 = sin (2π + 120) = sin 120 = sin (π - 60) = sin 60 = √3/2
Thus,
The solutions of the equation are:
x = 60 degrees
x = 120 degrees
x = 420 degrees
x = 480 degrees, and so on.

What is the volume of the cone?
A)240 cubic units
B)321 cubic units
C)48X cubic units
D)647 cubic units
Answer: cubic units.
Step-by-step explanation:
You can use this formula for calculate the volume of a cone:
Where "r" is the radius and "h" is the height.
You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:
Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:

what is there value of y?
what is the value of x?
Answer:
x=14
y=30
Step-by-step explanation:
5x+25=3x+53
5x=3x+28
2x=28
x=14
2y+35=95
2y=60
y=30
(I assumed all of the angles are equal, correct me if I'm wrong.)
Answer:x=14
Step-by-step explanation:
Let's first understand what we need to do. We need to solve for two variables, x and y. We do these by setting two systems of equations equal to each other. This is easily done for x, but for y the other equation is missing. Keep this in mind for later.
So, we will first start off by solving for x. We do this by using inverse operations.
5x+25=3x+53 We will subtract
5x=3x+28
2x=28 Divide
x=14
You can plug 14 into both the xs and they will be similar, and both will have the similar results once you solve for y and plug it into the equation along with x.
We know that the 5x+25 on the left is adjacent to 2y+35, and so is the second x. Adjacent angles add up to 180 total, and so to solve for y we need to plug 12 in the first x.
5(14)+25=95
180-95=85
85 is the value of 2y+35
We will solve for y just like any other alegrbaic problem
85=2y+35
50=2y
y=25
We know know that y is 25 and x is 14
Plug both values into 2 adjacent angles and they will add up to 180.
Answer:
This would be .0051 as an ordinary number.
Step-by-step explanation:
In order to turn this into a normal number, simply move the decimal place the same amount of times as the exponent.
So this would result in .0051
