Answer:
1560 cubic inches
Step-by-step explanation:
18x20= 360
360x13= 4680
4680/3=1560
The decimal representation of 1/11 is 0.090909...
The pair of digits '09' repeat forever.
If you start counting the digits after the decimal point,
the odd ones are all zero, and the even ones are all 9 .
So the 44th digit after the decimal point is 9 .
The angle of elevation from the hiker to the park ranger is the same as the angle of depression from the ranger to the hiker, 29°.
The tangent function of an angle is the ratio of the opposite side (500') to the adjacent side (x) in the right triangle shown. That is
tan(29°) = 500' / x
Multiplying the equation by x/tan(29°) gives
x = 500' / tan(29°)
x ≈ 500' / 0.5543
x ≈ 902 ft
Answer
Since sin x= cos (90- x)
Sin40=cos(90-40)
Sin 40=cos 50
X=50
the answer is 1 over 7225 if u want to know use cymath
