Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
Answer:
The candidate should get 5829 votes.
Step-by-step explanation:
This is a proportion question. The ratio should hold for both the pole and the actual vote.
Equation
x /9570 = 67/110 Multiply both sides by 9570
x = 67 * 9570 / 110 Multiply the two numerators.
x = 641190 / 110 Divide by 110
x = 5829
Yes as long as the sum of all the numbers equals 360°
