Answer:

75.3 degrees ( to nearest tenth).

Step-by-step explanation:

If we take a section through the plane BCHE we get a rectangle.

BC = 2 cm and BE = √(7^2 + 3^2). ( By the pythagoras theorem).

tan < BCE = √(7^2 + 3^2) / 2.

So the m < BCE = 75.3 degrees.

lorasvet [3.4K]

Answer:

(B)Enlarge by scale factor of 3 about the origin. Then translate 1 right.

Step-by-step explanation:

For the end point (3,4)

If we enlarge (3,4) by a scale factor of 3 about the origin, we have: (9,12)
If we then translate 1 right, we have :(10,12)

Similarly for the end point (4,5):

If we enlarge (4,5) by a scale factor of 3 about the origin, we have: (12,15)
If we then translate 1 right, we have :(13,15)

The correct option is B.
