Let l length, w width, p perimeter:
l=12+w
2(l+w)=p
2((12+w)+w)= 100
2(12+2w)=100
12+2w=50
2w=38
w=19
l=12+w=12+9= 21
l=21
Okay so this is easy conversion.
40 quarters=10$
60 dimes =24 quarters
30 dimes= 12 quarters=3$
200 dimes=80 quarters
Answer:
56 meters.
Step-by-step explanation:
Please find the attachment.
Let the leaning tower's be h meters tall, when it was originally built.
We can see from our attachment that the side with length 55.86 meters is hypotenuse and h is adjacent side for 4 degree angle.
Since we know that cosine relates the adjacent and hypotenuse of a right triangle.
Upon substituting our given values we will get,
Therefore, the leaning tower was approximately 56 meters, when it was originally built.
