You can consider the tree perpendicular to its shadow, therefore you get a triangle rectangle of which you know the two legs and you need to find the angle between the shadow and the hypothenuse, opposite to the tree.
In this case, the angle α can be easily found with trigonometry:
tan α = (opposite side / adjacent side)
Therefore:
α = tan⁻¹ (tree / shadow) = tan⁻¹ (10 / 14) = 35°
NOTE:
tan⁻¹ is sometimes found written as arctan.
Answer:
B, "it has one solution"'
(2,-1)
Answer:
Step-by-step explanation:
b increased by 16 is at most 20 in equation form
increased means add
b+16
is at most means 
Answer: Just simply solve the problem, i'm sorry but i cant see the problem do you think you could just copy the question down?
Step-by-step explanation:
The answers are choice A) and choice C). They effectively say the same thing but in a slightly different way. Choice A is more algebraic while choice C is more visual.
