The height of the tree is the sum of the part below the line parallel to the horizontal and the part above the line parallel to the horizontal.
Height of the part below the line parallel to the horizontal = 18 sin16° = 4.96 meters
Horizontal distance of the tip of the of the shadow from the tree = 18 cos16° = 17.30 meters
Height of the part above the line parallel to the horizontal = 17.3 tan68° = 42.83 meters
Height of the tree = 4.96 + 42.83 = 47.79 meters
Answer: 
Step-by-step explanation: Given that
and 
lies in Quadrant III.
We are to find the value of 
We will be using the following trigonometric identities:
We have
Since lies in Quadrant III, so tangent will be positive.
Thus,
No. Round 146 to 150 and add both 270 and 150. It's 420. So 400 would be more reasonable. 300 is not reasonable because it ain't close.
