The absolute value of any number is the positive value.
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.
17.5
This is because if you do the math: (7/40)*100 you get 17.5!
So divide 7 by 40 and then multiply it by 100!
7/40=0.175
0.175*100=17.5
