I believe it is Since the square root of 9 = 3 and the square root of 16 = 4 it is known the the square root of 12 is in between 3 and 4. Really hope this helps!
The equation for the given sequence representing the diameter of the circle is
f(n) = f(n-1) + 0.6, where f(1) = 2.5
Given, a sequence of diameters of a circle used to create an art project
2.5 , 3.1 , 3.7 , 4.3
We have to find a sequence that represents the diameter of the given circle,
Let f(n) be representing the diameter of the circle,
Now, for n = 1
f(n) = 2.5
for n = 2
f(n) = 3.1
for n = 3
f(n) = 3.7
for n = 4
f(n) = 4.3
As, f(2) = f(1) + 0.6 and so,
So, f(n) = f(n-1) + 0.6
Hence, the equation for the given sequence representing the diameter of the circle is
f(n) = f(n-1) + 0.6, where f(1) = 2.5

Answer:
x = 15°
Step-by-step explanation:
<em><u>The segment is a diameter, So let us assume the part in which there lies the triangle as a semicircle.</u></em>
=> <em>A triangle inscribed in a semi-circle will always have one of its angle equal to 90</em>
=> <em>So the angle (not 75 and x) is 90 degrees.</em>
<em>=> To find the value of x, we'll subtract rest of the angles from 180 degrees (because the interior angles of a triangle add up to 180°)</em>
<em>So,</em>
=> x = 180-90-75
=> x = 15°
