From the latter, we obtain the equation 1 radian = (180π)o . This leads us to the rule to convert radian measure to degree measure. To convert from radians to degrees, multiply the radians by 180°π radians .

What are the resulting coordinates of triangle X′Y′Z′ after rotating triangle XYZ counterclockwise 90° about the origin? Question options:
A) X′ (1, 1), Y′ (1, 4), Z′ (–4, 4)
B) X′ (1, 1), Y′ (4, 1), Z′ (4, 4)
C) X′ (1, 1), Y′ (1, 4), Z′ (4, 4)
D) X′ (–1, 1), Y′ (1, 4), Z′ (4, –4)
Answer:
C
Step-by-step explanation:
Rotation 90 degrees counter clockwise rule (x,y) -----> ( -y , x )
In order to find the answer we must first find the coordinates of the pre image
The coordinates are...
x (1,-1)
y (4,-1)
z (4,-4)
Now we apply the rule stated previously
( The rule explanation: the x and y values swap and the y values sign changes. So if the y value was previously positive, after a 90° counter clockwise rotation, the y value will then be negative)
x (1,-1) -----> swap x and y values ( -1,1) ------> flip sign of new x value ( 1 , 1 )
y (4,-1) ------> swap x and y values ( -1,4) -----> flip sign of new x value ( 1 , 4 )
z (4,-4) -----> swap x and y values ( -4,4) ------> flip sign of new x value ( 4,4)
the new coordinates are X' (1,1) , Y' (1,4) , Z (4,4)
Hence the answer is C

Find X segment of circles
Answer:
x = 88/45
Step-by-step explanation:
square of tangent segment = produce of entire secant and segment of secant outside circle
(GH)² = GS × GW
(13)² = 9(5x + 9)
169 = 45x + 81
45x = 88
x = 88/45

Twelve more than x is greater than
two
A. 12x>2
B. 12/x < 2
C. x + 12>2
D. 12-x>2
Answer:
C. x + 12 > 2
Step-by-step explanation:
Given:
Twelve more than x is greater than two
Required:
Translate to symbols
Solution:
Twelve more than x can be represented as "x + 12"
Greater than is represented by the symbol ">"
Two represented as "2"
Therefore, the translation to symbols would be:
x + 12 > 2

What is the range of fat grams for the five sandwiches?
15162121.224 ____________________Solution :-Given Information :-Highest grams fat in sandwich ➢ 33 gLowest grams fat in sandwich ➢ 9 gTo Find :-Range of fat grams for the five sandwiches. Formula Used :-Range = Highest limit - Lowest limit Calculation :-⇒ Range of fat grams for the five sandwiches = 33 - 9
Calculating further, We get,
⇒ Range of fat grams for the five sandwiches = 24 g
Since, 24 is also given as option E. 24. Therefore, option E. 24 is the correct answer.

Find the length of the hypotenuse of the triangle.
1mm 4/5mm c
Answer: 169/225 (0.75 2d.p)
Step-by-step explanation:
c²=a²+b² as C is Hypotenuse (largest side)
c²=(1/3)² + (4/5)²
c²= 1/9 + 16/25
c=169/225

find the area of the kite.
A. 27 square units
B. 40 square units
C. 18 square units
D. 36 square units
Answer:
36 unit^2.
Step-by-step explanation:
The area is the sum of the 2 triangles with each having base between the points (-2,4) and (-2,-4).
The base is4 - -4 = 8.
Area of a triangle = 1/2 * base * height.
Area of the kite = 1/2 * 8 * 3 + 1/2 * 8 * 6
= 12 + 24
= 36.

Answer:
Table 1(red)
Step-by-step explanation:
A proportional relationship will have a constant of proportionality between y and x all through the data given.
Constant of proportionality, k = y/x
Table 1 (red):
y/x = 5/1 = 10/2 = 20/4 = 5
k = 5 all through, therefore, this table show a proportional relationship between x and y
Table 2 (blue):
y/x = 1/6 ≠2/9 ≠ 4/15
This doesn't have a constant of proportionality, k, that is the same all through in the given table of values. Therefore, it doesn't show any proportional relationship between x and y
In the diagram, point C represents the center of the sphere. Diego says that the part of the sphere labeled D is the radius. Gregoire says that the part of the sphere labeled D is the diameter of the sphere.
A sphere. C is the center and D is the diameter.
Who is correct and why?
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Gregoire is correct; the diameter is a chord that is from the center to the surface of the sphere.
Diego is correct; the radius is a chord that passes through the center of the sphere.
Diego is correct; the radius is a chord that is from the center to the surface of the sphere.
Answer:A
Step-by-step explanation: edg 2021
Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.
What is a sphere?It is a three-dimensional figure where the volume is given as 4/3 πr³
We have,
The diameter of a sphere is a chord that passes through the center of the sphere and has endpoints on the surface of the sphere.
Therefore, the part of the sphere labeled D in the diagram is the diameter, not the radius.
The radius of a sphere is a chord that is from the center to the surface of the sphere, and it is half the length of the diameter.
Thus,
Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.
