Bought 3 pants for $29.99 each with a 10% coupon and 5% sales tax

29.99 one plant 10% off is 26.99  adding the sales tax it will be 28.34$

each plant would be worth 28.34$

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
