Answer:

28.7 meters

Step-by-step explanation:

Draw a diagram.  Let's say d is the distance between the anchor and the bottom of the tower, h is the height of the tower, and x is the length of the wire.

Using trigonometry, we can write two equations for the height of the tower:

h = d tan 65°

h = (d + 25) tan 35°

Setting these equal, we can solve for d.

d tan 65° = (d + 25) tan 35°

d tan 65° = d tan 35° + 25 tan 35°

d (tan 65° − tan 35°) = 25 tan 35°

d = 25 tan 35° / (tan 65° − tan 35°)

d ≈ 12.12

Now we can find x:

cos 65° = d / x

x = d / cos 65°

x ≈ 28.7

The wire is approximately 28.7 meters long.

First you need to multiply the cost of the vases times 2. Then you need to add the sales tax to the cost of both vases. The total would end up being $8.52. Next you subtract 8.52 from 28.50. You would get 19.98. Then lastly you it by three. So the cost of 1 package of glass beads is $6.66.
