PLEASE HELP! replace x with 5 and y with 12. you get 289 for the first one and 168 for the second one. when replacing one or both of the variables with zero we get the same answer. please explain why. ps replacing x, y with any other value other than 0 gives me different answers im looking for an explanation why that is.

(x + y)^2

x^2 + y^2

Answers:

so your question is asking to replace both expressions' variables with one or both of the two variables with zero, or replacing one of the variables or both of the two variables with only one expressions' variables?

PS: check your question again, can't udnerstand what you mean

Step-by-step explanation:

(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

536
