Answer 4

i think 82 is not correct because sin\(\theta\) can never be greater than 1
Created with RaphaëlReply Using Drawing

here AB represents tree
and BC represents the shadow
and \(\theta\) is the angle of elevation of top of tree

so sin\(\theta\) will be=\(\Large \frac{perpendicular}{hypotenuse}\)=\(\Large \frac{AB}{AC}\)

find AC using Pythagoras theorem
and you already know AB=50

then just substitute these values to get \(sin\theta\).

Answer 5

I used Pythagorean Theorem and I got 90.14 as the hypotenuse

Answer 6

yes correct and now substitute the values of AB and AC to get sin\(\theta\)
