Yes. Multiplying anything by a number less than one will decrease the original number. So multiplying two decimals will result in a number less than either one.
After moving all the terms to the right of the equation and solving you would get A = -36/49. Hope this helps!
tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
