What is the difference in length between a 1 1/4 and 3/8

7/8

Step-by-step explanation:

1 1/4 is the same as 5/4.

5/4 is also the same as 10/8.

The distance from 3/8 to 10/8 is 7/8.

Hope that helps

1 1/4 - 3/8

5/4 - 38

10/8 - 3/8

7/8

(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

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
