Is trapezoid abdc the result of a dilation of trapezoid mnpq by a scale factor 2/5 ?

C

Step-by-step explanation:

No, because AB is 2/5 the length MN but CD is 1/3  the length QP.

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

(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
