Answer:

Step-by-step explanation:
Please refer to the attachment.
By AA Similarity, the two triangles are similar.
Therefore, corresponding parts of them are proportional.
Therefore, we can write the following proportion:

We will solve for x. Cross-multiply:

Distribute:

Subtract 21 from both sides:

Divide both sides by 7. So, the value of x is:

However, that is only the value of x.
The shadow of the tree is (x+3).
Hence, we will need tot add 3 to our value. Therefore, the actual length of the shadow of the tree is approximately:

Answer: (should be) A
Step-by-step explanation: I've done the same test before
Answer: 3/6 and simplfied is 1/2
Answer:
1050
Step-by-step explanation:
1. divide using long division
put 2 outside and the 2100 inside
then from there 2 goes into 2 once so put that on top. Next 2 cant go into one so put a zero above the one. After that 2 goes into 10 5 times so put a 5 above the first zero in 2100. Lastly 2 goes into zero 0 times so put a zero above the second zero.
Answer with Step-by-step explanation:
We are given that a, b, c and x are elements in the group G.
We have to find the value of x in terms of a, b and c.
a.
