A, B and C are inner angles in a triangle. If A= B+ C, what can't be the size of B?
Choose one: A) 90 DEGREES B) 70 DEGREES C) 760 DEGREES D) 940 DEGREES E) 940 DEGREES
Given A= B+ C, and A, Band Care inner angles in a triangle. Thus A+ B+ C= 180   B+ C+ B+ C= 180 =&gt; 2(B+ C) = 180 =&gt; B+ C= 90. Thus beta will be less than 90.   Hence the answer is 90 DEGREES.
