Answer:

y = 1

Step-by-step explanation:

4 - (y-3) = 3(y+1) - 4(1 - y)

4 -y +3 = 3y + 3 - 4 + 4y

7 - y = 7y - 1

7 + 1 = 7y + y

8 = 8y

8/8 = y

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

Answer:

Height of tree= 13.8m

Step-by-step 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.
