Answer:
A) tan(45°) help us to find the height of the tree because it relates our unknown with a known length (the length of the shadow)
B) tan(45°) = x/35.6
C) x = 35.6 ft
Step-by-step explanation:
B) From definition:
tan(45°) = opposite/adjacent
opposite to angle 45° is x ( the height of the tree), adjacent to angle 45° is the length of the shadow (35.6 ft). Replacing into the equation:
tan(45°) = x/35.6
C) tan(45°) = 1
Then:
1 = x/35.6
35.6 ft = x
Answer:
Ellie is correct because 1,483 and 1,454 would round up to 1,500 but the 1,250 would round up to 1,300
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Given x and y are in proportion then the equation relating them is
y = kx ← k is the constant of proportion
To find k use an ordered pair from the table
Using (2, 10 ), then
10 = 2k ( divide both sides by 2 )
5 = k , thus
y = 5x ← relationship between x and y
