Given that the base of the triangle is x m, the height is 3m less than twice it's base then the height will be represented by the equation:
(2x-3) m
thus the area will be:
Area=1/2bh
Area=1/2x(2x-3)=17.5
x^2-1.5x=17.5
writing the above equation is quadratic form of ax^2+bx+c=0 we get:
x^2-1.5x-17.5=0
Now, for a rhombus, all sides are the same length, and the diagonals bisect the vertex they cut, so they cut them in halves, and they also meet at right-angles, and cut each other in halves as well
that means, if the angle is 108, the shorter diagonal will cut that in two equal angles, of 54 each, check the picture below
and since they each other cut in halves where they meet, one side of the shorter diagonal will then be half of 9, or 9/2 or 4.5
since the angle is in degrees, make sure your calculator is in Degree mode
The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
<h3>How to determine the rock's height?</h3>
The function is given as:
d = √216 +h²
At a distance of 100 feet, it means that:
d = 100
So, we have:
√216 +h² = 100
Take the square of both sides
216 +h² = 10000
Subtract 216 from both sides
h²= 9784
Take the square root of both sides
h = 98.9
Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
