if the sin of angle x is four fifths and the triangle was dilated to be two times as big as the original, what would be the value of the sin of x for
According to the given statement the value of sin x = 8/10
What is trigonometry?A mathematical field called trigonometry examines connections between triangles' sides and angles. Due to the fact that every straight-sided shape can be decomposed into a group of triangles, trigonometry can be found throughout all of geometry.
How is trigonometry applied in the real world?To roof a home, to make the roof slant (in the case of single-family bungalows), to determine the height of a roof in buildings, etc., use trigonometry. The naval and aviation industries use it. It's applied to cartography (creation of maps). Trigonometry is also used in satellite navigation systems.
According to the given information:sin x = 4/5
We know that:
Sin x = opposite/Hypotenuse.
So,
When the triangle is enlarged, the opposite side will increase to an angle of 8, and the hypotenuse will increase to an angle of 10.
= 4/5 we multiply by 2 with 4 and 5 we get:
= 8/10
4/5 will result from simplifying 8/10. Thus, nothing has changed.
So the value of sin x = 8/10.

Three partners x,y and z con an amount of kush 1400000 for an investment .The profit from the investment is to be shared based on contribution of each.A profit of kush 250000 after one month.If x got 60000 ,y 110000 and the remainder was Z. Calculate the ratio of the contribution
Answer:
The ratio of the contribution in the order x:y:z is;
6:11:8
Step-by-step explanation:
Herr, we want to know the ratio of the contribution
The title profit is 250,000
What Z got will be;
250,000-60,000-110,000 = 80,000
So the ratio of the contribution following x,y,z will be ;

Answer:
see attached
Step-by-step explanation:
To plot the line through the point, plot the point. Then find another point that has the given "rise" and "run". Draw the line through the two points.
__
The given point is (-7, -4). Locate that on the graph.
The slope is given as -2/3. This is the ratio of "rise" to "run", so it means the "rise" will be -2 for each "run" of 3. (rise/run = -2/3)
The rise is the vertical change. So, you want your second point to be 2 units below the given point. Its y-coordinate will be -4-2 = -6.
The run is the horizontal change. Your second point will be 3 units to the right of the given point, so its x-coordinate will be -7+3 = -4. Now, you can plot the point (-4, -6) and draw your graph through these two points.
If you take a number, times by 3 then subtract 6. You get the same as if you took the number, times by 7 then subtract 2. What is the number?

one number is two more than triple a second number. Their sum is 30. what is the smaller number
Answer:
7
Step-by-step explanation:
We can solve this problem by making an equation.
Let x represent the second number
3x + 2 will be the first number because it is 2 more than triple x
This makes our equation:
3x + 2 + x = 30
Combine like terms
4x + 2 = 30
Subtract 2 from both sides
4x = 28
Divide both sides by 4
x = 7
The smaller number aka the second number is 7

A line has an undefined slope and passes through the poimt (7,11) write the equation of the line
Answer:
x = 7
Step-by-step explanation:
An undefined slope indicates the line is vertical and parallel to the y- axis with equation
x = c ( c is the value of the x- coordinates the line passes through )
the line passes through (7, 11 ) with x- coordinate 7 , then
x = 7 ← equation of line

What is an Algebraic expression?
An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is as below,
1/2 (-1.4m + 0.4) = ?m +0.2
Suppose the unknown number be x.
Then the given expression can be written as,
1/2 (-1.4m + 0.4) = xm + 0.2
=> -0.7m + 0.2 = xm + 0.2
=> -0.7m = xm
=> x = -0.7
Hence, the missing number in the given expression is -0.7.

The value is approximate.
==========================================================
Explanation:
Focus on the upper triangle.
Label the unknown horizontal side as y
Use the pythagorean theorem to solve for y
a^2+b^2 = c^2
10^2 + y^2 = 26^2
100+y^2 = 676
y^2 = 676-100
y^2 = 576
y = sqrt(576)
y = 24
-----------
Now move to the bottom triangle
With respect to the reference angle, the side y = 24 is opposite this. The hypotenuse is unknown.
Use the sine rule to connect the two and solve for x
sin(angle) = opposite/hypotenuse
sin(32) = y/x
sin(32) = 24/x
x*sin(32) = 24
x = 24/sin(32)
x = 45.2899179551967 which is approximate
x = 45 rounding to the nearest whole number
Side x is approximately 45 cm long.
Note: make sure your calculator is in degree mode.

4 - 2a = 16
-2a = 16 - 4
-2a = 12
a = 12/-2
a = -6
a - 2b = b
-6 - 2b = b
-6 = b + 2b
-6 = 3b
-6/3 = b
b = -2
b - 2c = a
-2 - 2c = -6
-2c = -6 +2
-2c = -4
c = -4/-2
c = 2
a - 2d = c
-6 - 2d = 2
-2d = 2 + 6
-2d = 8
