1.
by definition, the sum of the measures of all three angles in triangle is °
°
if the sum of the measures of ∠ and ∠ is °, then
°.....solve for °
°
2. let consecutive integers be and ,
if the result of adding the smaller integer () and triple the larger integer ()is , we have
....solve for ...first integer
...second integer
so, answer is B. ,
