Jack and Jill got tired of falling down that hill with a pail of water and decided to try flying a kite instead. Jack is holding

the kite string, and Jill is standing directly under the kite. The kite string forms a 61° angle with the line of sight between Jack and Jill, who are the same height. The two BFFs are standing 12 yards apart. How long is the kite string?

Because Jill is standing directly under the kite the angle between jack Jill and the kite is 90°
so
a=12 yards
A°=61°
B°=90°
b=?
to find b we have a formula:
a devided by the sinus of A equals b devided by the sinus of B

12÷sin(61°)=b÷sin(90°)
12÷0.8=b÷1
15=b

How do I do this? It is a regular hexagon with a height of 30. We have to find the perimeter of it.
Sliva [168]

Answer:

The radius of a hexagon is called the apothem, which in this case is 15.

We need to know the side length which is found by the equation:

side length = apothem * 2 * (tan (180 / #sides))

side length = apothem * 2 * (tan (180 / 6))

side length = 15 * 2 * (tan (30 degrees))

side length = 30 * .57735

side length = 17.3205

We need the perimeter of the hexagon which equals the side length times six.

perimeter = 6 * 17.3205 = 103.923

The intersection of 2 planes can be defined as a_____?
tamaranim1 [39]

The intersection of two planes is a line.   That's not necessarily the definition of a line, but that's probably what they're looking for.
