Answer 1

8. Obtuse

11. Obtuse

Explanation:

c^2 = a^2 + b^2

for 8, it's 6 squared plus 9 squared, which is 117. now, 15 squared is 225. 225 is bigger than 117, which makes it obtuse. if the two results equaled each other, it would be a right triangle. if the 2 smaller numbers when squared were bigger than the hypotenuse squared, then it would be acute
