A 15-ft ladder is propped against a vertical wall and makes a 72 ̊ angle with the ground. How far is the foot of the ladder from
murzikaleks [220]
We first approach this problem by illustrating the situation. Refer to the diagram attached.

From the diagram, we can clearly see that we need to simply solve for the length marked x in order to find the distance between the foot of the ladder to the base of the wall.

Remember SOHCAHTOA. We can apply here the concept of cosine since we have the angle. Incorporationg x into the equation, we can simply make use of the relation cosine 72° = adjacent/hypotenuse.

cos(72deg)= \frac{x}{15}
15cos(72deg)=x
x=4.6

ANSWER: The distance between the foot of the ladder and the base of the wall is 4.6 feet.

Anybody know the answer?
maks197457 [2]

We know that the sum of measures of internal angles in each quadrangle is 360°.

Look at the picture.

\alpha+\beta+\gamma+\delta=360^o\ \text{and}\ \delta+\tau=360^o\\\\\text{therefore}\\\\\alpha+\beta+\gamma+\delta=\delta+\tau\ \ \ |-\delta\\\\\alpha+\beta+\gamma=\tau

Therefore we have:

\theta=35^o+83^o+23^o=141^o

Answer: θ = 141 deg.

A recent survey asked 100 randomly selected adult Americans if they thought that women should be allowed to go into combat situa
Gnesinka [82]

Answer:

(a) The probability of a "Yes" answer, given that the person was a female is 0.16

(b) The probability that the respondent was a male, given that the response was a "No" is 0.3

Step-by-step explanation:

This problem can be solved using the definition of conditional probability

P(B|A) = P(A∩B) / P(A)

(a) In this case, event A is that the person is female and event B is that the answer of the person is "Yes".

P("Yes" | Female) = P(Female ∩ "Yes") / P(Female)

P("Yes" | Female) = (8/100)/(50/100)

P("Yes" | Female) = 8/50

P("Yes" | Female) = 0.16

(b) In this case, event A that the answer of the person is "No" and event B is that the person is male.

P(Male | "No") = P("No" ∩ Male) / P("No")

P(Male | "No") = (18/100)/(60/100)

P(Male | "No") = 18/60

P(Male | "No") = 0.3
