Answer:
74.05 degree
Step-by-step explanation:
A ladder leans against a building. The foot of the ladder is 2 feet from the building and reaches to a point 7 feet high on the building.
The ladder forms a right angle triangle with the building
Base of the triangle is 2 feet
The distance between the ground and the top of the ladder is 7 feet
the graph is attached below
AB= 2, AC = 7
We know the opposite and the adjacent side so we use tan formula
x = tan^-1 (7/2)
x = 74.05 degree
Answer:
endpoint is (29, -13)
Step-by-step explanation:
Formula for midpoint is
So, let be the coordinates of the endpoint you are looking for.
and
= (10, -3)
-9 + = 20 7 +
endpoint is (29, -13)
Answer:
0.999
Step-by-step explanation:
At least 1 correct means, 1 correct, 2 correct, 3 correct ... until 10 correct. That would be a long process to calculate.
<em>Instead we use the complement rule to calculate.</em>
<em></em>
<em />
<em>So we need to find P(x<1). So this is getting 0 answers correct, or 10 incorrect.</em>
<em />
In true false question, probablity of correct is 1/2 and incorrect is 1/2, hence,
Probability of 10 incorrect is (1/2)^10
Thus,
So the answer is 0.999 (rounded to nearest thousandth)
