All the spiders and ants in Aunt Melly's attic have a total of 152 legs and 22 heads. How many spiders and how many ants are in the attic.

(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

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

they can both be solutions depends on the equation
