Question

Please answer quickly ( answer is 8 degrees) I just need to know how to work it out

Answer 1

see explanation

Explanation:

Subtract 4.2 from the height of the original 34 m, that is

height of remaining tree = 34 - 4.2 = 29.8 m ← hypotenuse of triangle

sinΘ =
`(opposite)/(hypotenuse)` =
`(4.2)/(29.8)`, thus

Θ =
`sin^(-1)`(
`(4.2)/(29.8)`) ≈ 8° ( nearest degree )
