Answer:
24.72 m
11.53 m
Step-by-step explanation:
Horizontal distance AB can be obtained from △ABC
From trigonometry :
Sin18° = opposite / hypotenus
Sin18° = AB / 80
AB = 0.3090169 * 80
AB = 24.72 m
The height BT, of tower from △ABT
From trigonometry :
Tan25° = opposite / Adjacent
Tan25° = h / 24.72m
h = Tan25 * 24.72
h = 11.527
h = 11.53 m
Hence, height of tower BT = 11.53 m
Answer:
80 countries participated in the 1980 olympics in Moscow.
Step-by-step explanation:
Hello, I think I can help you with this
You can solve this by using a simple rule of three
Step 1
define
140 countries participated in 1984,this was 75% more than the last time,this means that 140 is the 175% of a value that we need to know
if
140 ⇔175%
x? ⇔100%
the relation is
Step 2
solve for x
80 countries participated in the 1980 olympics in Moscow.
Have a nice day
