Using proportions, it is found that the value of x is of x = 5, hence option A is correct.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Since the triangles are similar, the lengths are proportional. Researching the problem on the internet, we have that the proportions are given as follows:
- A side with a length of x is proportional to a side with length 25.
- A side with a length of 3 is proportional to a side with length 15.
Hence:
Simplifying the denominators:
x = 5.

The sequence for the nth term is (6n+6)+1
Hence the 77th term would be
( 6(77) + 6 ) + 1
=469
Answer:
Mostly millimeter
Step-by-step explanation:
Length has several unit like m,cm, mm, feet, miles, inches, km etc
we measure the length in units which is more understandable or readable. like thickness of mobile is around 3mm to 1cm or we can even measure in inches like .5inch but if we measure it in meter or feet it will be difficult to understand, read and write similarly the unit of length most suitable for measuring the height of a backyard tree is meter or feet because the length of tree is around 10 feet to 25 feet or 2meter to 6meter if we measure the length in cm or mm or in inches then it will be difficult to understand, read and write.
17 inches
15^2 + 8^2 = 289
square root of 289 = 17 inches
