Answer:
2.5477 feet
Step-by-step explanation:
Refer the image attached to understand my solution.
BC = height of lamppost.
DE = Julia
AD = shadow of Julia
BD = 2 feet. AD = 5 feet
BA = BD + AD
= 2 + 5 = 7 feet
In ΔABC
tan 20° =
BC = 7 * tan 20°
BC = 2.5477 feet
SO the height of lamppost = 2.5477 feet
is there more information to the question??
its not true the answer is -17 i dont know if thats what your looking for
6) 15 + 2x = 75 Check: 15 + 2x = 75
2x = 75 - 15 15 + 2*30 = 75
2x = 60 15 + 60 = 75
x = 60/2 75 = 75
x = 30
7) m/3 - 14 = 10
m/3= 10 + 14
m/3 = 24
m = 24 *3
m = 72
