One angle of a triangle is obtuse. The sum of the measures of the other angles must be A. more than 90 degrees B. less than 90 degrees C. equal to 90 degrees help i need this 10 points please

B.less than 90 degrees

Step-by-step explanation:

Obtuse angle is greater than 90°

Since the sum of all 3 angles= 180°

The sum of other 2 angles less than  180°-90°= 90°

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
