Answer:
You need more information. But typically multiplly by 100 so .1 would be 10 %
Step-by-step explanation:
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
approx. 24.6 ft
2 and 3/4 is a mixed number and the decimal of it is 2.75
Doubling the side length multiplies the area by 4
