Answer:
53.13⁰
Step-by-step explanation:
Use sine:
sinθ=opposite/hypotenuse
sin∠A=4/5
∠A=sin⁻¹(0.8)=53.13010235415≈53.13⁰
Answer:A
$14.5
Given data
Cost for the visit=442.25 Rubles
exchange rate
3 USD= 91.5 Rubles
but 1 USD= 91.5/3
= 30.5
Therefore if 1 USD is 30.5 Rubles
Then xUSD is 442.25 Rubles
cross multiply
30.5x= 442.25
divide both sides by 30.5
x= 442.25/30.5
x=14.5USD
The cost of the attraction is $14.5
3+5 = 8
240/8 = 30
30*3 = 90 red cars
