Answer:
61.97 feets
Step-by-step explanation:
Using trigonometry :
Horizontal distance between the person and building,
Let distance = d
Tan 15 = 15 / d
0.2679491 * d = 15
d = 15 / 0.2679491
d = 55.980781
To obtain the height, h :
tan 40 = (h-15)/d
d = 55.98
h-15 = 55.98 (tan 40°)
h - 15 = 55.98 * 0.8390996
h - 15 = 46.972797
h = 46.972797 + 15
h = 61.972797
h = 61.97 feets
Answer:
ln (27 x²)
Step-by-step explanation:
Given in the question an expression
3 ln 3 + 2 ln x
Step1
Apply power rule
ln 3³ + ln x²
Step2
Apply multiplication rule
ln (3³ . x²)
3³ = 27
so
ln (27x²)
