Answer:
Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
Step-by-step explanation:
Given:
Radius of the Earth = 3,960 miles
Find:
Surface area of Torrid Zone (cylinder shape) = ?
Computation:
We know that, distance between two tropics is 3,250 miles.
So, Height = 3,250 miles
Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
There's an identity
sec^2 x = 1 + tan^2 x
so here we have
sec^2 theta = 1 + (3/8)^2 = 73/64
sec theta = sqrt 73 / 8 or 1.068 to nearest thousandth
Answer:
x = 38°
Step-by-step explanation:
Complementary angles = 90°
90° = x + x+14
90° = 2x + 14
104 = 2x
x = 52°
the next angle should be 52 - 14 = 38°
So x = 38°
