M, N and O are inner angles in a triangle. If M= N+ O, what can't be the size of N?
Choose the correct choice from the following answers:	A) 90 DEGREES	B) 60 DEGREES	C) 960 DEGREES	D) 960 DEGREES	E) 9660 DEGREES
Given M= N+ O, and M, N and O are inner angles in a triangle. Thus M+ N+ O= 180   N+ O + N+ O= 180 =&gt; 2(N+ O) = 180 =&gt; N+ O= 90. Thus beta will be less than 90.   Hence the answer is 90 DEGREES.
