Quadrilateral a’b’c’d’ is a dilation of quadrilateral abcd about point p with a scale factor of 2 1/2 .

a. enlargement

b. reduction

A. Enlargement

Step-by-step explanation:

We are given that,

Quadrilateral ABCD is dilated by a scale factor of .

Now, we know that,

If 'k' > 1, then the dilated figure is enlarged in size.

If 0 < 'k' < 1, then the dilated figure is reduced in size.

Since, the given scale factor is .

Hence, option A is correct.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
