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.
Out of every two consecutive numbers one will always be even. There is only one even prime number. Whether there are an infinite number of pairs of primes which differ by two (the twin prime conjecture) is still open e.g. 3 , 5; 41 , 43 ; 101 , 103 .
Answer: 5 + 47 = 108
Step-by-step explanation: dont worry it works
Answer:
They are a Pythagorean triple that forms a right triangle
Step-by-step explanation:
a2 + b2 = c2
(5)^2 + (12)^2 = (13)^2
25 + 144 = 169
(13)^2 = 169
