Answer: a dilation and a rotation

Step-by-step explanation:

  • A reflection is a rigid transformation that maps every point of a figure in the plane to point of image of figure, across a line of reflection .
  • A rotation of some degrees is a rigid transformation which rotate a figure about a fixed point known as the center of rotation.
  • A translation is a rigid transformation of a figure that moves every point of the figure a fixed distance in a particular direction.
  • A dilation is a transformation in which a figure is enlarged or reduced with respect to a point known as the center of dilation.

From the given figure it can be seen that ΔABC is reduced to ΔA"B"C" so there must be dilation.

Also, when there is rotation about point C to create ΔA"B"C".

Therefore, the transformations could have occurred to map ΔABC to ΔA"B"C" are a dilation and a rotation.

The answer is 90 + 45 because BOC is a right angled triangle where angle BOC is 90 and angle BOK is 45 because 90 ÷2. A OK Is a right angled triangle so angle AOB is 90 as well so to find angle AOK we plus 90 and 45 which is 135 degrees.

Solve 2x2 + 5x = 12
Delvig [45]

Answer:

A

Step-by-step explanation:

2x² + 5x = 12

2x² + 5x - 12 = 0

x² + 5x - 24 = 0

factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3

2x² - 3x + 8x - 12 = 0

split the equation and factor

2x² - 3x = 0 ||| 8x - 12 = 0

x(2x - 3) ||| 4(2x - 3)

therefore the pair is (2x - 3)(x + 4)

2x - 3 = 0

2x = 3

x = 3/2

or

x + 4 = 0

x = -4

Use quadratic formula to find the solutions to the quadratic equation 2x^2-3x+6=0
defon

Answer:

2x² - 3x + 6 = 0

a = 2 b = -3 c = 6

delta = b² - 4ac = 9 - 4.2.6 = -39

=  > x =  \frac{3 +  \sqrt{39}i }{4}  \: or \: x =  \frac{3 -  \sqrt{39} i}{4}

ppositional angle closure in eyes with narrow angles: comparison between the fellow eyes of acute angle-closure glaucoma and nor
skad [1K]

Here is the comparision

Purpose:To compare the topologic features of acute primary angle-closure glaucoma eyes before an attack to those of normotensive eyes, assuming that untreated fellow acute primary angle-closure glaucoma eyes are candidates for an acute attack.

Methods:Under dark-room conditions, ultrasound biomicroscopy was used to examine 50 eyes (12 fellow eyes of acute primary angle-closure glaucoma and 38 normotensive cases with a closure-possible narrow angle). Before any surgical or laser intervention, all eyes were examined and found to have normal pupillary response without the use of any topical drugs. Each eye was examined at four predetermined angle locations. The chamber angle configuration parameters were measured and compared between the two groups.

Result:Appositional angle closures were detected in 27 fellow eyes and 48 normotensive eyes with a closure-possible narrow angle. The incidence differed statistically between the two groups (69.2% in fellow eyes and 48% in normotensive eyes). In the fellow eye group, appositional angle closures beginning at the angle's entrance were more frequently detected. The distance between the iris root and the bottom of the angle varied significantly between groups.

Conclusion:Acute primary angle-closure glaucoma fellow eyes have different topologic features than normotensive narrow-angled eyes, as well as a higher incidence of appositional closure, which may predispose these eyes to an impending acute attack.
