The height of the tree which is the opposite side of the right triangle is 145 meters.
<h3>How to find height when given angle of elevation?</h3>
The angle of elevation is 36 degrees.
The situation forms a right angle triangle.
Therefore,
base of the triangle = 200 m
Hence, using trigonometric ratios,
tan 36 = opposite / adjacent
tan 36 = x / 200
x = 200 tan 36
x = 200 × 0.726542528
x = 145.308505601
x = 145.31 m

If you have 150 total gift cards, and 130 are worth 5$, 15 are worth 50$, that would leave five 100$ gift cards for a sum of 150 gift cards.
All you would do is divide the 5/150 = 30
There's a 30% chance that someone will get a 100$ gift card.
