The leaning tower of Pisa currently "leans" at a 4 degree angle and has a vertical height of 55.86 meters. How tall was the lean
Marizza181 [45]

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}}

Upon substituting our given values we will get,

\text{Cos (4)}=\frac{55.86}{h}

h=\frac{55.86}{\text{Cos (4)}}

h=\frac{55.86}{0.99756405026}

h=55.996\approx 56                      

Therefore, the leaning tower was approximately 56 meters, when it was originally built.

HELLPP "Which table represents a linear function?"
Flura [38]

Answer:

1st option

Step-by-step explanation:

The equation for the 2nd option will be y = 1/x which is a hyperbola

The equation for the 3rd option is I'm unsure because it is not linear as it does not have the same jump between the y values

The equation for the 4th option is not linear as it does not have the same jump between the y values

Hope this helped and have a good day
