Answer:
(0,0)
Step-by-step explanation:
You can draw a right triangle with theses measures:
elevation angle = 42°
base = adjacent angle = distance from the base of the three to where the man is standing.
height = opposed angle ≈ height of the tree = 20 feet.
Note: this is assuming that the elevation angle is from the ground (this is the man is looking laying on the ground).
=> tan(42) = opposed angle / adjacent side => 20 feet / x
=> x = 20 feet / tan(42) = 22.21 m
Answer: option C. 22,2 feet
Are u supposed to finish the sentence or..? Cause i dont get the question
He is wrong because if a + b > c it doesn't follow that a^2 + b^2 > c^2
(a + b^2 will always be greater than c^2 but a^2 + b^2 will not always be.
.
An example:
Right angled triangle with sides 3, 4 and 5:-
3 + 4 > 5 but 3^2 + 4^2 = 5^2
