The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:
... d = √((3 in)² +(13 in)²) = √(9+169) in = √178 in
The tangent of the angle you want to find is the ratio of the height of the box to this length:
... tan(α) = 4/√178
Taking the arctangent, we have
... α = arctan(4/√178) ≈ 0.291285 radians
Answer:
I got A.
Step-by-step explanation:
It is b because you round to the nearest 100 and I got it right on the quiz
I hope this helps you
length =width +1.25
Area =length ×width
320=w. (w+1.25)
w=18.625
l=19.875
