Which composition of transformations maps figure RSTUV to figure R"S"T"U"V"?
Sergeu [11.5K]

Answer:

option: B is correct

A reflection across line n followed by a 270° rotation about point P.

Step-by-step explanation:

Clearly from the figure we could see that the graph is first reflected across the given line n such that we obtain the figure R'S'T'V'U' and then it is rotated 270° across the point P so that we obtain the figure R"S"T"U"V".

Hence, option B is correct.

( A reflection across line n followed by a 270° rotation about point P )

Line CD is the perpendicular bisector of segment AB. The lines intersect
svetoff [14.1K]

Answer:

E is the same distance from A and B. ⇒ D

Step-by-step explanation:

<em>Let us explain the meaning of perpendicular bisector</em>

If line m is the perpendicular bisector of line n, then

  • line m intersect line n at the mid-point of line n
  • They form 4 right angles around this mid-point

∵ Line CD is the perpendicular bisector of segment AB

∴ Line CD intersects segment AB at the mid-point of AB

∵ Line CD and segment AB intersected at point E

→ That means E ∈ CD and E ∈ AB

∴ Point E is the mid-point of line AB

∴ Point E divides line AB into 2 equal parts

→ That means point E is at the same distance from points A and B

∴ E is the same distance from A and B.

Find the the Unknown sides (please help)
ololo11 [35]

Answer:

10) x = 8.12

12) x = 5.5

Step-by-step explanation:

10) Since the leg adjacent to the angle is given and the leg opposite to the angle needs to be figure out the Tangent ratio will be used which states Tan(32°) = \frac{x}{13} and simplified, will give the answer 8.12 to the nearest hundreths.

12) The leg opposite to the right angle is given which means that its the hypotenuse. The hypotenuse is given and the side adjacent to the angle needs to be figured out so Cosine ration will be used. Which states; Cos(60°) = \frac{x}{11}. Simplified further will give the value of 5.5 exact.

Hope this helped, Good Luck!
