ok... so there are no equal angles so its scalene...

and the 100 angle tells you the type pf scalene...

so what type of angle is 100..?

the anwser choices are :
A. acute
B. equiangular
C obtuse
D right

Answer 5

so wouldnt it be C?

Answer 6

or would it be acute....

Answer 7

You were right at first, obtuse.

100 is an obtuse angle. If any angle is obtuse(greater than 90) then it is obtuse.

An acute triangle is only when all 3 angles are acute
