5 distinct streets connecting cities X and Y directly. 3 separate streets connecting cities Y and Z.
2 separate streets connecting cities X and Z directly.

How many are the possible routes connecting cities X and Z directly?​

answer: 25 is the correct answer

step-by-step explanation:

(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

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
