CAN SOMEONE HELP WITH NUMBER 9 PLZZ

i think so

Step-by-step explanation:

if you flip the pockets  on each other they are the same and im pretty sure thats what congrueant means no?

they are congruent

Step-by-step explanation:

if you place them side by side you can see that the pockets are mirrored from each other

(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
