In , R, S, and T are midpoints.

4. If H = 50 and I = 66, find ITS.

To find the value of ITS, we need to use the concept of midpoints. In this question, it is given that R, S, and T are midpoints.

Let's break down the information given:

- H = 50: This means that the midpoint R is 50.

- I = 66: This means that the midpoint S is 66.

Now, we need to find the value of T, the third midpoint.
Since R, S, and T are midpoints, they divide the number line in equal parts. To find T, we need to find the value that divides the remaining part of the number line (after R and S) equally.

The distance between R and S is the same as the distance between S and T. We can find this distance by subtracting the value of R from S or vice versa.

The distance between R and S = S - R = 66 - 50 = 16.

Since R is 50, the distance between R and T is also 16. We can find T by adding 16 to the value of R.
T = R + 16 = 50 + 16 = 66.

Therefore, the value of ITS is 66.
