the height of the ladder touching the wall =
√(20²- 4²)
=√ (400-16)
=√384
= 8√6 feet
or 19.6 feet
Answer:
68 yards
Step-by-step explanation:
P=2l+2w (l=length, w=width)
318=2(91)+2w
318-182=2w
2w=136
width=68yds
A because it’s the only one that makes the best sense
B does not make sense it is the opposite of what ur trying to find
C is not a correct percentage, the correct Percentage would be 53.84%
D which can’t be correct because choice b and c are not correct
Answer:
So the triangle adds up to 180
