Given:
One midsegment of an equilateral triangle.
To find:
The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.
Solution:
All sides of an equilateral triangle are same.
Let a be the each side of the equilateral triangle.
Length of the midsegment is equal to the half of the non included side or third side.

The sum of two side is

Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is





Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.
Answer:
Yes
Step-by-step explanation:
Multiplicative Inverse of rational number:
When we multiply a rational number and its multiplicative inverse, we get 1

Now,multiply this with (3/-17)

So, -5 2/3 is the multiplicatice inverse of 3/-17
