I think its A please dont get mad if its wrong
Ummm this confuses me a bit
The question was posted incomplete.
This is the part missing:
<span>What is the height of the plane to the nearest meter?
Answer: 559 m.
Explanation:
1) The horizontal distance between the plane and tha atoll makes a right triangle with the height, with the depression angle between the two legs.
2) Therefore, you can use the tangent trigonometric ratio:
tan(10°) = opposite-leg / adyacent-leg = height / horizontal distance
⇒ height = horizontal distance × tan (10°)
⇒ height = 3,172 m × tan(10°) = 559.31 m, which rounded to the nearest m is 559

A. To be able to have the 2 sides ( the 2 triangles) line up correctly, Net A would be the correct one.
B. AB = 3
BC = 5
CD = 9.4
C. Surface area:
9.4 x 5 = 47
9.4 x 3 = 28.2
9.4 x 4 = 37.6
3 x 4 = 12
Total: 47 + 28.2 + 37.6 + 12 = 124.8 sq. in.
