Atree that is 10 yards tall and casts a shadow 14 yards long. find the angle of elevation from the tip of the shadow to the top of the tree. round to the nearest degree -54 degrees - 36 degrees - 46 degrees - 44 degrees

36 degrees

Step-by-step explanation:

Refer the attached figure .

Height of tree i.e. AB = 10 yards

Length of shadow i.e. BC = 14 yards .

We are required to find the angle of elevation from the tip of the shadow to the top of the tree. i.e. ∠ACB

Now, we will use trigonometric ratio.

Thus the angle of elevation is 35.52° ≈ 36°

Hence  the angle of elevation from the tip of the shadow o the top of the tree. i.e. ∠ACB  is 36°

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

the answer is a if my teacher taught me correct
