Gabriella said a triangle with an angle of 98 degrees was an obtuse angle. cynthia said a triangle with an angle of 98 degrees was an acute triangle. who is right and why?

An obtuse triangle has an angle that is greater than 90 degrees

so if we see gabby's statement, ,98>90 so tecnically, she is correct

cynthya's statement is false because 98>90 so it is an obtuse angle

A= r2 × 3.14 11×11 ↓ ↓ 121 × 3.14 = 379.94 → 379.9

Graph a should be your answer
