Answer:
D. The gliding or sliding of every point in the plane in the same direction.
Step-by-step explanation:
We know that 'Translation' is a rigid transformation in which the image or figure is moved in any direction'.
Now, since an image in the co-ordinate plane is formed by a number of co-ordinate points.
This means that when we translate a figure, we shift all the points responsible in making the figure in the same direction.
Hence, the key feature of a translation is the gliding or sliding of every point contributing to the figure translated in the same direction.
5.7 is the answer because if one side is 7.9 the parallel is the same a rectangle. The is you add those, you get 15.8. The equation now is 15.8+x=27.2. 27.2-15.8 is 11.4 which is then divided to find the two sides which makes them 5.7.
Answer:
420 cm²
Step-by-step explanation:
Given the width is x then the length is x + 8 ( 8 longer than width )
Given the perimeter = 90 cm
Sum the lengths of the sides stating at the top left corner and going clockwise
Noting that the indentation small part is 8 - x
x + 8 + x + x + 8 - x + 8 + x + x + 8 + x + x + 8 - x + 8 + x
= 6x + 48
Equating perimeters
6x + 48 = 90 ( subtract 48 from both sides )
6x = 42 ( divide both sides by 6 )
x = 7
Thus width = 7 cm and length = 7 + 8 = 15 cm
The figure is made of 4 rectangles, thus
area = 4 × (7 × 15) = 4 ×105 = 420 cm²
Answer:
Figure A sides are 1/4 the size of Figure B
The top of Figure A = 4, the top of Figure B = 1.
Divide 1 by 4 to get the scale factor, which is 1/4 as a fraction or 0.25 as a decimal.
Step-by-step explanation:
Answer: m∠2 = 160°, m∠3 = 20°.
Step-by-Step Explanation: We know that m∠1 = 160°.
The values of both m∠1 and m∠2 are equivalent, which means that m∠2 is also 160°. The interior angles of a rhombus always add up to 360°, and when we add both 1 & 2, we get 320°.
The <em>other</em> opposite ends of a rhombus's interior measures are also the same in value. ... To figure out what m∠3 is, let's do the following steps:
1. 360-320 = 40
This means that the remaining two angle measurements will add up to 40°.
2. 40/2 = 20.
The final missing angle; m∠3 = 20°.
3. There, done!! Good luck!
