If the quotient is positive, we know that the two integers are either both positive or both negative.
If the quotient is negative, we know that one integer is positive and the other is negative.
If the quotient is zero, then we are dividing 0 by some non-zero integer.
Sin < C = 63/65 so m < C = 75.75 degrees
and tan B = 16/63 so m <B = 14.25 degrees
m < C + m<B = 75.75 + 14.25 = 90 degrees
Therefore m < A = 180-90 = 90
therefore the triangle is right-angled.
The first one can be written as a fraction because it is a repeating decimal.
The second one can be written as a fraction because it is a repeating decimal.
The third one can not be written as a fraction since it is nether terminating nor repeating.
The last one can be written as a fraction since it is a terminating decimal.
Their radii, their diameters, their circumference, and their area will all be proportionate. But I think that all circles are proportionate.
