THE ANSWER OF THIS QUESTION IS 9
Answer:
54?
Step-by-step explanation:
Answer: None
Step-by-step explanation:
There are no pairs of congruent sides, so the triangles cannot be proven congruent.
The gcf of 42 and 70 is 14
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!
