The coordinates of the image after a rotation of 180° counterclockwise about the origin is A' ( 7 , 3 )
What is Rotation?The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.
90° clockwise rotation: (x,y) becomes (y,-x)
90° counterclockwise rotation: (x,y) becomes (-y,x)
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
270° clockwise rotation: (x,y) becomes (-y,x)
270° counterclockwise rotation: (x,y) becomes (y,-x)
Given data ,
Let the coordinate of the point be A
Now , the value of A is A ( -7 , -3 )
And , 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)
So , the coordinates of the image is A'
And , the value of A' = A' ( 7 , 3 )
Hence , the rotation is solved and the image is A' ( 7 , 3 )

Find the slope of the line
Answer:
Undifined
Step-by-step explanation:
One of the legs of a right triangle measures 1 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
3.9 cm
Step-by-step explanation:
One of the legs of a right triangle measures 1 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
We can solve the above question using Pythagoras Theorem
Hypotenuse ² = Opposite ² + Adjacent ²
From the above question
Hypotenuse = 4 cm
1 leg = Opposite = 1 cm
Other leg = Adjacent = x
Hence
4² = 1 ² + x²
x² = 4² - 1²
x = √ 16 - 1
x = √15
x = 3.8729833462 cm
Approximately to the nearest tenth = 3.9 cm
The measure of the other leg is 3.9 cm

Answer:
a) KJL = 76⁰
b) LKM = 76/2 = 38⁰
Answer:
∠KJL = 76°
∠LKM = 38°
Step-by-step explanation:
since arc KL = 76°, ∠KJL also = 76° because central angles are congruent to their arcs.
∠LKM = 1/2 arc KL = 1/2(76°) = 38°

Find the circumference of a circle with an area of 1809.56 square centimeters
Answer:
150.8cm
Step-by-step explanation:
Area= π r²
make r subject of the formula
A = π r²
A/π= πr² (dividing both sides by π)
r²= A/ π
r =
[tex] \sqrt{ \frac{a}{\pi} } [/tex]
r=√(1809.56)/(π)
r=√576.0008
r≈24cm
:. circumference= 2π r
= 2× π × 24
=150.7964

simplify: ,3(x-2) + 2(2x+5) =32, a+2a+7a
Answer:
x = 4, 10a
Step-by-step explanation:
3(x-2) + 2(2x+5) = 32
3x - 6 + 4x + 10 = 32
3x + 4x + 10 - 6 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
Divide both side by 7
x = 4
a + 2a + 7a
They are common because the have the same variables.
'a' is with a coefficient of 1
You add the coefficient and attach the variable to it
Therefore,
a + 2a + 7a = 10a

Step-by-step explanation:
A relation is a function if and only if each element of the range, corresponding with y-axis, is associated with only one element of the domain, corresponding with x-axis. In this case, the graphed relation is not a function, since for all element of the domain, except 0, are related to two distinct elements of the range.

Order the side from greatest to least.
Η.
28°
118°
K
J
side [Select ]
Answer:
HJ>KJ>HK
Step-by-step explanation:
Side opposite to the largest angle is the largest.
Side opposite to smallest angle is the smallest.
ang K = 118° ang J = 28°
ang K + ang J + ang H = 180° (Sum of all the angles in the triangle is 180°)
118°+28°+angH=180° (Putting the values of ang K & ang J)
146°+angH=180°
ang H=180°-146°
ang H=34°
128°>34°>28°
ang K>ang H>ang J
Here, ang K is the largest, so the side opposite to it i.e. HJ will be the largest side.
Smaller than ang K and bigger than ang J is ang H, so the side opposite to it i.e. KJ will be smaller than HJ but bigger than HK.
Ang J is the smallest angle, so the side opposite to it i.e. HK will be the smallest.
HJ>KJ>HK.
