-87 is the correct answer
Answer:
x is 46.67
y is 28.4°
Step-by-step explanation:
To solve for x we use sine
sin ∅ = opposite / hypotenuse
AC is the opposite
x is the hypotenuse
so we have
sin 59° = 40 / x
x sin 59 = 40
Divide both sides by sin 59
x = 40/sin 59
x = 46.67
To solve for y we also use sine
sin y = 30/ 63
y = sin^-1(30/63)
y = 28.4°

Answer:
8 hours 456 miles
1 hour 456/8 miles
456/8=57
I used a calculator here so you can check
so,
1 hour is 57 miles
12 hours will take (57)(12)=684 miles
The answer is 684 miles
Hope the explanation and the answer helped you
Answer:
(n/4) - 5 = 2(n-14)
Step-by-step explanation:
let the number be n
"25% of n" : (25/100)n = n/4
"Five less than 25% of n" : (n/4) - 5
"difference between the number and 14" : n - 14
" twice the difference between the number and 14" : 2(n-14)
Assembling all the parts:
(n/4) - 5 = 2(n-14)
