Answer:

Solution,

∆ ACB = ∆ EFD

finding the value of X,

$\frac{x}{3.8} = \frac{15}{5}$

Apply cross product property

$x \times 5 = 15 \times 3.8$

Calculate the product

$5x = 57$

Divide both sides by 5

$\frac{5x}{5} = \frac{57}{5}$

Calculate

$x = 11.4$

Hope this helps...

Good luck on your assignment...

In a rigid transformation, the shape of the image remains the same as the preimage

The correct options are;

Rotation; a → b

Translation: a → d

Reflection over a horizontal line: c → e

Reflection over a vertical line: g → f

Rotation then reflection: a → h

Rotation then translation: e → j

The reasons why the above selections are correct are as follows;

Rotation; Figure a is rotated about a common center to figure b to move from a to b

Translation: Figure a can be translated towards the left and then upwards to reach figure b

Reflection over a horizontal line: A reflection over a horizontal line is similar to a reflection across the x-axis, therefore an example of a reflection over horizontal line is c → e

Reflection over a vertical line: A reflection over a vertical line will turn a left pointing triangle to a right pointing triangle as shown in g → e

Rotation then reflection: The preimage is first rotated about an axis before it is then reflected as seen in the clockwise rotation figure a about its axis, followed by a reflection across a vertical axis to figure h

Rotation then translation: The rotation and translation composite transformation can be seen in figure e which is rotated to point left, and then translated into the position of figure j

WILL GIVE BRAINLIEST PLEASE HELP: In rectangle ABCD the diagonals intersect each other at point O and m ABD = 30 degrees. Find B

NISA [10]

Answer:

AngleCOD=angle AOB=62°

As AO=OC=BO=OD

In triangle OCD, OC=OD

Hence angle ODC=(180–62) /2( sum of angle of triangle is 180°)

=118/2 =59°
