Find the value of x.
Answer:
x = 50°
Step-by-step explanation:
A triangle has total interior of 180 degree .
x + 84° + 46° = 180°
x = 180° -46° -84°
x = 50°
In the given triangle, the value of x is determined to be 50°. In other words, The value of x in the triangle is 50°.
To find the value of x in a triangle with angles measuring 84°, 46°, and x°, follow these steps:
Step 1: Recall that the sum of the angles in a triangle is always 180 degrees.
Therefore, the sum of the three angles in the given triangle is:
[tex]84 + 46 + x = 180[/tex]
Step 2: Combine like terms and isolate x.
Start by subtracting 84 and 46 from both sides of the equation:
[tex]84 + 46 + x - 84 - 46 = 180 - 84 - 46[/tex]
[tex]x = 50^{\circ}[/tex]
Step 3: The value of x is 50. This means that the third angle in the triangle measures 50°.
By applying the fact that the sum of angles in a triangle is 180°, set up an equation and solve for x.
The equation represents the sum of the given angles (84°, 46°, and x°) equating to the total sum of angles in a triangle (180°). By simplifying the equation, obtained x = 50, which indicates that the third angle in the triangle measures 50°.Learn more about triangles here:

what is the correct equation
Answer: y = 0.4x
In fraction form, this is y = (2/5)x
================================================
Explanation:
For each row, divide the y over x values
Row One: y/x = 0.8/2 = 0.4Row Two: y/x = 4/10 = 0.4Row Three: y/x = 6/15 = 0.4Row Four: y/x = 10/25 = 0.4We end up with the same thing each time.
Since y/x = 0.4, this rearranges to y = 0.4x
Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4

Travis spies an owl in a tall tree. He estimates the height of the tree to be 85 feet and the angle of elevation to the bird from where he stands to be 68°. The leaves on the tree make it difficult for Travis to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Travis step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot.
Please help!!
Answer:
63.44 feet
Step-by-step explanation:
tan(68 degrees)= 85/y
y tan (68 degrees)=85
y=85/tan(68 degrees) ( cross multiply)
y = 34.34 feet
tan (41 degrees)=85/x+y
(x+y)tan(41 degrees)=85
x+y=85/tan 41 degrees
x=85/tan(41 degrees) - y
x= 85/tan (41 degrees)-(34.34) (cross multiply)
Therefore, Travis stepped back 63.44 feet to gain a better view!

[tex]19\ 227\ 000\ m^{3}[/tex]
Step-by-step explanation:
The equation for volume of a rectangular prism is
[tex]V = \frac{hB}{3}[/tex]
[tex]B = lw[/tex]
V is volume
B is base
so if the base measures 522 multipled by 500

In this polygon, all angles are right angles.
What is the area of this polygon?
Enter your answer in the box.
=========================================================
Explanation:
Draw a vertical line through the middle to split the figure into two rectangles.
The rectangle on the left is 21 ft by 7 ft. Its area is 21*7 = 147 sq ft.
The rectangle on the right is 24-7 = 17 ft by 21-10 = 11 ft. The area is 17*11 = 187 sq ft.
The combined area is therefore: 147+187 = 334 square feet
-------------
A different approach:
Draw a horizontal line through the middle to form two rectangles.
The rectangle on top is 10 ft by 7 ft with area of 10*7 = 70 sq ft.
The rectangle on the bottom is 24 ft by 12-10 = 11 ft, so its area is 24*11 = 264 sq ft.
Total area = 70+264 = 334 square feet
--------------
Yet another method:
Draw a horizontal line through the top most edge of the figure. Do the same for the right-most side of the figure. The two lines meet in the top right corner. This will form a rectangle that is 21 ft tall and 24 ft wide.
The area of this big new rectangle is 21*24 = 504 sq ft.
However, we don't want all of this area. We'll kick out the rectangular piece that is 10 ft tall by 24-7 = 17 ft across (in the upper right corner). The area we want to kick out is 10*17 = 170 sq ft.
The actual area we want is 504 - 170 = 334 square feet
There are probably other methods you could use to find the area of this figure.

Compare the slope of the following equation and graph by determining which line is steeper.
A. The line represented by the equation has the same steepness as the line shown in the graph.
B. The line represented by the equation is steeper than the line shown in the graph.
C. The line shown in the graph is steeper than the line represented by the equation.
D. There is not enough information to determine the steepness of the lines.
Answer:
The equation is in the form y = mx, where m represents the slope.
So, the slope of the line represented by the equation is .
Use two points from the graph to determine the slope of the line shown on the graph.
The calculation shown below uses the points (0, 0) and (1, -2).
So, the slope of the graph is -2.
To determine which line is steeper, compare the absolute values of the slopes. The line whose absolute value of the slope is greater is the steeper line.
Therefore, the line shown in the graph is steeper than the line represented by the equation.
