Answer:

(a) Reflection and rotation

Step-by-step explanation:

The order of the vertices in the original polygon CDEF is clockwise. The order of vertices in the image polygon GEIH is counterclockwise. This means a reflection is involved in the transformation. Rotation with or without translation will not reverse the orientation.

The only choice that includes reflection is ...

A reflection and a rotation

A reflection alone cannot do the transformation shown. A reflection together with rotation and/or translation will do it. For example, reflection across the y-axis, and 90° counterclockwise rotation about the point F'. Or, reflection across the line y=-x and translation right 3 and down 1.

Answer:

A rotation and a translation

rotation

Step-by-step explanation:

Again, we have to rotate to make the shape fit in, right?

But it wouldn't fit... Or will it? If you can take 2 guesses, you can try the rotation and a translation or the rotation.

Sorry, I'm also getting confused at some point :(!

If both triangles are similar the ratio of sides will be same

$\\ \sf\longmapsto \frac{x}{24} = \frac{6}{12} \\ \\ \sf\longmapsto 12x = 6 \times 24 \\ \\ \sf\longmapsto 12x = 144 \\ \\ \sf\longmapsto x = \frac{144}{12} \\ \\ \sf\longmapsto x = 12$

What additional piece of information is needed to show that DEF = PQR by ASA? E F R. line DF=line PR FER ZDELP Oline EF=line QR

Rina8888 [55]

Answer:

Given: PR=EF, QR=DE and PQ=FD

Now, In △PRQ and △DEF

PR=EF

QR=DE

PQ=FD

Thus, △PQR≅△FDE (SSS rule).

In triangle ABC, it is given that angle A is 59 degrees and angle B is 53 degrees. The altitude from B to line AC is extended un

dsp73

Answer:

∠AKB = 22°

Step-by-step explanation:

Call the point of intersection of BK and AC point P. Then line BK is a transversal to parallel lines AK and BC. Alternate interior angles AKB and PBC will be congruent.

We know that angle PCB is 68°, the difference between 180° and the sum of the two given angles in ΔABC:

∠PCB = 180° -∠PAB -∠ABC = 180° -59° -53° = 68°

Since PB is an altitude, ∠CPB is a right angle. Then ∠PBC is the complement of ∠PCB, so is ...

∠PBC = 90° -68° = 22°

As we said, this is congruent to ∠AKB, so ...

∠AKB = 22°

Corn costs $2 for 6 ears. Carmen bought 24 ears of corn. How much did she spend?

katrin [286]

Carmen bought $8 of corn. Carmen bought 24 wars of corn but 6 ears of corn cost $2. 24 divided by 6 is 4. Which means Carmen bought 4 sets of 6 ears of corn. As Carmen bought four sets of 6 ears of corn, you multiply 4 times the $2 to get your price, which is $8. Ending with the solution that Carmen spent $8.
