(c) a prime number (d)an even number

A Irrational number

Step-by-step explanation:

Explanation

Pi is strictly a irrational number , as it is not in the form of . i.e not a fraction

Pi is consider from the ration of circumference of circle to its diameter .

and its value is Pi = 3.14159 ,but this value is not repeating

But in case of its value is 3.142857142857... i.e is this value is reapating its self ,

And is a rational number, as it is in the form of

and if we subtract from a irrartional number then the resultant is also irrational

Hence we can say that PI - is a irrational number.  Answer

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
