Question

Can someone tell me if my answer to this problem is correct, please? And if it isn't how do you solve it? ​

Answer 1

Height of tree= 13.8m

Explanation:

When finding the value of a in your working, I suggest to leave the answer to 5 significant figures so that your final answer is more accurate. The value of a should be 26.048m to 5 s.f.

Then multiplying 26.048 with sin 32° would give you 13.8m too when rounded off to 3 significant figures :)

I have attached my working too.
