The values of x is 82° , z is 98°and y is 69°. in the given triangle.
Is the sum of all triangle angles always 180 degrees?Because one outside angle of a triangle is equal to the total of the other two angles in the triangle, the angles of a triangle add up to 180 degrees. In other words, the third angle must join with the other two angles in the triangle to generate a 180-degree angle (the two angles that add up to form the outside angle).
we know that the sum of angle of triangle = 180
so,
x+ 60 +38=180
x=180-8
x=82°
and also
x+z = 180
z= 98°
for value of y
13 + 98 +y = 180
y= 69°

Find the slope (2,2) and (6,8)
Therefore the slope of the line joining the points (2,2) and (6,8) is equal to 2/3.
What is meant by slope?
A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).
The formula for finding the slope of a line is [tex]m= \frac{X2-X1}{Y2-Y1}[/tex].
Where (X1, Y1) and (X2, Y2) are the points on the line.
The given points are (2,2) and (6,8).
Therefore slope is

Typically, a teragon will be bounded by one or more self-similar fractal curves, which are formed by replacing each line segment in an initial figure with multiple interconnected parts, then substituting each of those parts with the same pattern of segments, then repeating the process an infinite number of times for every line segment in the figure.

In the above scenario, note that the total distance of the flight is given as: 48.4 miles (approximately). This is solved using the law of Sines to find x.
What is the law of Sines?The connection between the sides and angles of non-right (oblique) triangles is defined by the Law of Sines. Simply put, it asserts that the ratio of the length of a triangle's side to the sine of the angle opposite that side is the same for all triangle sides and angles.
Thus, with regard to the problem modeled in the attached triangle, because two angles are given, the missing angle is 180° − (157° + 8°) or 15°. Use the Law of Sines to find x.
Using the law of ins we can state that:
Sin 8°/x = sin 15°/90
90 (Sin 8°) /x = Sin 15°
90 Sin 8° = x Sin 15°
90 Sin 8° / Sin 15° = x
90 (0.13917310096)/ 0.2588190451 = x

The alternative hypothesis[tex](H_1)[/tex]is less than 71.3% of American families owned their homes.
b) The type I error is the null hypothesis is true but we assumed it to be false that is 71.3% or more of American families owned their homes but the council did not provide tax breaks.
