I don't see anything, but any line that doensnt have the right angle sign is not perpendicular.
Answer:
681 feet
Step-by-step explanation:
Let x represent the distance between campsite and the base of the cliff.
We have been given that Haylee hikes to the top of a 120-foot vertical cliff. From the top of the cliff, the angle of depression to her campsite is 10∘. We are asked to find the distance between campsite and the base of the cliff.
We can see that angle of depression forms a right triangle with respect to ground, cliff and campsite.





Upon rounding to nearest foot, we will get:

Therefore, the campsite is 681 feet away from the base of the cliff.

Answer:
666
Step-by-step explanation:
From this question,
a = 1-99%
a = 1-0.99
a = 0.01
5% = z(0.05) = 2.58 when we check the standard normal table
Therefore we calculate n as:
n = (z/E)²*p*1-p
Z = 2.58
E = 0.05
P = 0.5
1-p = 0.5
(2.58/0.05)²x0.5x0.5
= 51.6²x0.5x0.5
= 665.64
Therefore n is approximately 666.
Answer:
A could work
Step-by-step explanation:
Because it is a square, all angles should be 90 degrees
