sorry I can't explain it properly, all you have to do is to dive the coefficient of x by 2 and square the result

Step-by-step explanation:
The cosine function, along with sine and tangent, is one of the three most common trigonometric functions. In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as 'cos'.
In any right angled triangle, for any angle:
The sine of the angle = the length of the opposite side
the length of the hypotenuse
The cosine of the angle = the length of the adjacent side
the length of the hypotenuse
The tangent of the angle = the length of the opposite side
the length of the adjacent side
So in shorthand notation:
sin = o/h cos = a/h tan = o/a

10.6 = 10.6 / 1
Numerator = 10.6 × 10 = 106
Denominator = 1 × 10 = 10
Numerator / Denominator = 106 / 10
The simplified fraction:
= 106/10
= 53/5
= 10 3/5
