Since triangle DEF = triangle JKL, m<D = m<J, m<E = m<K, m<F = m<L.
m<F = m<L = 90 degrees
m<K = m<E = 5(m<D)
but m<E + m<D = 90 degrees [right angled triangle]
5(m<D) + m<D = 90 degrees
6(m<D) = 90 degrees
m<D = 90 / 6 = 15 degrees.
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.
![\text{Cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Ctext%7BCos%7D%3D%5Cfrac%7B%5Ctext%7BAdjacent%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
Upon substituting our given values we will get,
![\text{Cos (4)}=\frac{55.86}{h}](https://tex.z-dn.net/?f=%5Ctext%7BCos%20%284%29%7D%3D%5Cfrac%7B55.86%7D%7Bh%7D)
![h=\frac{55.86}{\text{Cos (4)}}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B55.86%7D%7B%5Ctext%7BCos%20%284%29%7D%7D)
![h=\frac{55.86}{0.99756405026}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B55.86%7D%7B0.99756405026%7D)
Therefore, the leaning tower was approximately 56 meters, when it was originally built.
Answer:
I not sure this 76.5
Step-by-step explanation:
9cmx17cm=156/2=76.5
Then 76.5/2= 39

Answer: 2 1/2
Step-by-step explanation: Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction. Hope this helps!! PLZ mark me!!!
