Step-by-step explanation:
To determine what the height of the ladder reaches up the wall we need to know the height of ladder which is not provided in the question.
So if I assume the height of ladder to be 10ft( just a general assumption)
Then, inclined ladder, wall and distance been the bottom of the ladder and wall will form a right angle triangle.
where height of ladder will be hypotenuse, height of the ladder reaches up the wall will be perpendicular and distance been the bottom of the ladder and wall will be base.
Since, A ladder is inclined at 23 degrees against the wall
⇒ height of the ladder reaches up the wall = Height of ladder×sin23°
= 10ft × sin23° = 3.9073 ft
Answer:
I think the answer to the first question is "B"
and the second one is "D"
Step-by-step explanation:
To find the area of any rectangle you multiply length times width.
8,1/2*11
17/2*11/1
187/2
93.5 or 93, 1/2.
For the second bit you just divide 1000 by 93.5. 1000/93.5=10.7 So ten pieces. Hope this helps! <span />
