Two sides of a triangle measure 7cm and 15cm. Which could be the measure of the third side of the triangle?
2 answers:
Answer:
18 cm is the answer.
Step-by-step explanation:
We know by triangle inequality theorem that “The sum of any two sides of a triangle should be greater than the third side”.
Herr, 2 sides are given as 7 cm and 15 cm.
Let the third side of a triangle be x
According to the above statement:
Now, we can see that the length of the third side must lie between 1 cm and 18 cm to form a triangle if 7 cm and 15 cm are its other two sides.
So, the answer is 18 cm.

Answer:
Part 1:
Yes, the side lengths form a right triangle.
Part 2:
Option d 37.1 cm
Explanation:
We need to use the pythagorean theorem.
In part 1, if the 3 side lengths are a right triangle, then, they must verify:
By the theorem. Then:
They're equal, then the lengths correspond to a right triangle.
For part 2, we need to use again the theorem. In this case:
