We have a triangle, when:
hypotenuse=slant height=20 ft
opposite side=height of the tree=?
angle formed by the tree with the ground=72º
sin Ф=opposite/ hypotenuse ⇒ opposite=(hypotenuse)(sin Ф)
In this case:
oppssite=20 ft /sin 72º=19.021...≈19
Answer: the heigth of the tree is 19 ft.
The unit vector that is in the same direction as v is given by:
<h3>How to find a vector given two points?</h3>
The vector is given by the <u>terminal point subtracted by the initial point,</u> hence:
v = (-17, 4) - (7, -9) = <-24, 13>
<h3>How to find the unit version of a vector?</h3>
Each coordinate of the vector is <u>divided by it's norm</u>.
For this vector, the norm is given by:
Hence the unit vector is:

Answer:
<h2>x = 8 (Verified) ✅</h2>
Step-by-step explanation:
If we visualize the figure, we can see that sides LN and MP are going to be parallel and of the same length.
So x = 2x - 8
Subtract x
0 = x - 8
x = 8
Check the answer
8 = 2(8) - 8
8 = 16 - 8
8 = 8 ✅
