Answer:
The correct answer is 12.446 feet.
Step-by-step explanation:
A ladder leans against a building forming an angle of 50° with the ground.
The base of the given ladder is 8 feet away from the building.
Let the length of the ladder that is to be found be x feet.
Thus we find the cosine of the angle of inclination.
∴ cos 50° =
⇒ x = 12.446 feet
Therefore the length of the ladder is 12.446 feet.
eu não sei, desculpe companheiro, não me denuncie
1. divide all sides by 24 to save time.
37=21-20x
2. subtract 21 this both sides
16= -20x
3. divide both sides by -20
-16/20 = x
4. reduce to its lowest terms
-4/5= x is the answer
Answer:
-8
Step-by-step explanation:
-8
Answer:
x = 8
Step-by-step explanation:
The product of the length of the exterior segment of a secant and the length of the secant is equal to the correpsonding operation with the other secant.
9(9 + 11) = 10(10 + x)
180 = 100 + 10x
10x = 80
x = 8
