Answer:
approx. 24.6 ft
Step-by-step explanation:
x=the distance of the fire from the base of the tower
200ft=the height of the tower
7 degrees=the angle of depression
Using these values you can draw a diagram that highlights that you need to use trig. to work out the answer.
Using Tan:
Tan 7=x/200 ft
multiply both sides by 200 ft
200*tan 7=24.55691218
2 5/8 - 6 1/4 + 8 1/2\
= 227 /8
hope this helps :)
Yo sup??
a(n)=-5+6(n-1)
just put n=12
a(12)=-5+6*11
=61
Hope this helps
8a+9
You have to add the like terms.
4.5a+7+3.5a+2
4.5a+3.5a=8a
7+2= 9
