No, A is not correct. According to the Triangle Inequality Theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, the sum of the lengths of the two given sides is 10 mm + 7 mm = 17 mm. Therefore, the length of the third side must be greater than 17 mm, so none of the choices given (A, B, C, D) can be correct.
Two sides of a triangle are 10 mm and 7 mm. Using the Triangle Inequality Theorem, determine the length of the third side from the choices given. (1 point)
A. 5 mm
B. 2 mm
C. 1 mm
D. 20 mm
is A correct?
