Prime numbers have?
-less than two factors
-more than two factors
-exactly two factors
-less than or equal to two factors

exactly 2 factors

Step-by-step explanation:

they are 1 and itself

for example 3 is a prime number and its factors are 3 and 1.

(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
