Question 1 options:

A)

Can't be determined

B)

Obtuse

C)

Right

D)

Acute

Respuesta :

Answer:

b)   obtuse

Step-by-step explanation:

If this is a right triangle the hypotenuse would be

c² = 9² + 12²

c² = 81 + 144

c² = 225

c = √225

c = 15

Since the third side is 17 which is longer than 15

the triangle is obtuse

obtuse
