Answer: 33.6
Step-by-step explanation:
tan(angle) = opposite/adjacent
tan(40) = x/40
40*tan(40) = x
x = 40*tan(40)
x = 25*0.8390996312
x = 33.56398525
So the tree is roughly 33.6 feet tall
Answer:
y=x+11
x=7 because 25-4=21 and 21 ÷3=7
39.7%
(actual value - estimated value) / actual value
5.8 - 3.5 = 2.3
2.3 / 5.8 = 0.3965 = 39.65%
