Answer:
x=31
Step-by-step explanation:
3x+25+2x=180°
=5x=155°
x=155/5
x=31
<u>Given</u>:
The nth term of the sequence is defined as 
We need to determine the term
of the sequence.
<u>The term </u>
:
The term
can be determined by substituting n = 5 in the nth term of the sequence 
Thus, we get;

Simplifying the expression, we get;

Squaring the term, we have;

Multiplying the expression, we get;

Thus, the value of the term
of the sequence is 80.
I'm gonna assume that the 5s are $.
To find the mean, add all the numbers, then divide by the number of data points (5).
(2426+2463+1451+2154+1119)/5 = 1922.6
To find the median, put the data in order from least to greatest, then find the middle data point.
1119 1451 2154 2426 2463
To find the range, subtract the largest from the smallest:
2463-1119 = 1344
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.
