distance = 3280 feet. This is the triangle's hypotenuse.

The distance from the ground is the opposite side as it is opposite the angle 42˚


Sin = Opposite/Hypotenuse

Sin(42) = Opposite/3280   Answer: 2195 feet

Cross multiply

Opposite = sin(42) x 3280

Opposite = 2194.7 feet

This situation represents triangle with one angle of 90 degrees. That angle is directly below glider. That means that we can you basic trigonometry functions.

sin42 = h/3280

Now we express h.
h = 3280* sin42 
h = 2195 feet

The answer is 2195 feet.

Which is evidence that a convergent boundary once existed
Vladimir79 [104]

Volcanic islands, Mountain ranges

Explanation:

A convergent margin is plate boundary in which plates comes together. There are different types of interactions that occurs around a place where plate converges.

  • An ocean-continent convergence creates a subduction zone in which the denser oceanic plate sinks beneath the less dense continental crust.
  • As the oceanic plate begins to subside, it can melt and form chains of volcanic island within the riding continents.
  • Also, where two plates of equal densities converge, none of them subsides and this leads to upbuilding.
  • The product can be seen as extensive mountain ranges on earth like the Andes and Himalayas.
