Answer:
C
Step-by-step explanation:
12^2 = 144, 9^2 = 81, and 15^2 = 225.
144 + 81 = 225, therefore a^2 + b^2 = c^2.
13, 6+7=13 thats my answer :D
Answer:
No ABC is not a triangle
Step-by-step explanation:
Perimeter = 22 cm
AB = 8 cm ; BC = 8 cm
AC = 22 - ( 8 + 8 ) = 6 cm
But all those sides doesn't follow Pythagorean Theorem(AB^2 + BC^2 = AC^2) ....because 8^2 + 8^2 isn't equal to 6^2 ......
Had it followed the theorem , it could have been a right angle triangle...
