The sets M and F are given below. M= ( b, d, h) F= (d, e, j) find the union of M and F. Find the intersection of M and F. Write your answers using set notation (in roster form).

Step-by-step explanation:

Union of two set is the joining together o the two sets

Intersection of a set are the values which are common to all the given sets.

(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
