I dont know how to do this pls help

≈ 8.6 cm

Step-by-step explanation:

tan= opposite leg/adjacent leg

tan 43°= 8/b

0.933= 8/b

b= 8/0.933

b= 8.57449≈ 8.6 cm

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
