The ratio of height : shadow =44/1313
Therefore height of the tree,x=3434*(44/1313)
=115.08 ft
If you meant 13 and 34 as the length of shadows respectively, then also x=115.08 ft
2x + 3x + 140 = 360 (being complete turn angle)
5x + 140 = 360
5x = 360-140
5x = 220
x = 44
now 2x = 2 × 44 = 88
3x = 3 × 44 = 132
We have
<em>v</em> = (-7, 9) - (4, 3) = (-7 - 4, 9 - 3) = (-11, 6)
which as a linear combination of the <em>i</em> and <em>j</em> unit vectors is
<em>v</em> = -11<em>i</em> + 6<em>j</em>
