The answer is 0.51111111111111111 (It goes on for infinity).
Answer:
Option D is not a rational number
Step-by-step explanation:
A rational number is one that can be represented in the form of fraction like X/Y, where X and Y are integers and X ≠ 0. While an irrational number is one that cannot be expressed in the form of simple fractions.
For example, ¾ is a rational number while √3 is an irrational number.
Now to the question;
A) The product of 2 and 0.3333 gives;
2 × 0.3333 = 0.6666.
This can be expressed as a fraction as; 6666/10000.
Thus it is a rational number
B) The sum of 2 + √3 and 5 - √3 gives;
2 + √3 + 5 - √3 = 7
As a fraction, it can be written as; 7/1
Thus it is a rational number.
C) The sum of 37 and 12 is;
37 + 12 = 49
Can be expressed as; 49/1
Thus,it's a rational number.
D) Product of 2 and √2 gives;
2 × √2 = 2√2
It can't be expressed as a fraction with integers. Thus, it's not a rational number.
The first step to solving this is to use tan(t) =

to transform this expression.
cos(x) ×

Using cot(t) =

,, transform the expression again.
cos(x) ×

Next you need to write all numerators above the least common denominator (cos(x)sin(x)).
cos(x) ×

Using sin(t)² + cos(t)² = 1,, simplify the expression.
cos(x) ×

Reduce the expression with cos(x).

Lastly,, use

= csc(t) to transform the expression and find your final answer.
csc(x)
This means that the final answer to this expression is csc(x).

since complementary angles always add up to 90 degrees, subtract 90-36 and you get 54
the last one, 54.
