Which classification best represents a triangle with side lengths 6 cm, 10 cm, and 12 cm? acute, because 62 + 102 < 122
acute, because 6 + 10 > 12
obtuse, because 62 + 102 < 122
obtuse, because 6 + 10 > 12

C

Step-by-step explanation:

use Pythagorean theorem

+ =

c is the longest side

if + > then it's acute (greater than)

if + < then it's obtuse   (less than)

if they are equal, then its a right triangle

+ =

36 + 100 = 144

136 = 144

136 < 144   obtuse

d 600 because 15*10*2=300

300+300=600
