The most specific name is trapezoid
we are given with two numbers: 8 and 0.25. In this case, we are asked in the problem to determine the set in which the numbers belong to. 8 belongs to whole numbers and integers, as well as natural numbers. 0.25 belongs to decimal numbers and whole numbers
The value of tan a is 2.9098
Explanation:
The given value is 
Now, we shall find the value of sin (a), using the identity,

Substituting the value of cos (a), we get,

Subtracting both sides by 0.1056, we have,

Taking square root on both sides, we get,

Now, we shall substitute the value of sin (a) and cos (a) to determine the value of tan (a) in the identity 

Thus, the value of tan (a) is 2.9098
