BRAINLIEST, MEDAL, STARS!!! PLEASE HELP MAEEE! TRIANGLE INEQUALITY THEORM! which collection of three side lengths can be used to form a triangle?

A. 75 cm, 35 cm, 40 cm
B. 40 cm, 30 cm, 75 cm
C. 40 cm, 65 cm, 30 cm
D. 80 cm, 35 cm, 40 cm

Answer 1

C.  The Triangle Inequality Theorem States that any two sides of a triangle must be greater than the third side. It cannot be A because 35+40= 75, which is not greater than 75. It cannot be B because 40+30= 70, which is not greater than 75. It cannot be D because 35+40= 75, which is not greater than 80. It is C because 40+30= 70, which is greater than 65.
