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

D, because there might be values higher than 120, because the data points range from 0 - 200.
2x - y = 1
2x + y = 7
-------------------add
4x = 8
x = 2
2x - y = 1
2(2) - y = 1
-y = -3
y = 3
answer (1,3)
Check the picture below.
let's recall that a circle has 360°, so that means every two radii coming from the center of the hexagon, will split those 360° in 6 even pieces, 360/6 = 60, namely those two radii make up a 60° central angle, as you see in the picture.
running a perpendicular from the center, we end up with a 30-60-90 triangle, as you see there, and thus we can use the 30-60-90 rule to get the length of "a".
now, keeping in mind that the perimeter of the polygon is simply 4+4+4+4+4+4 = 24.
