Final answer:
The measure of RTV is 55 degrees.
Step-by-step explanation:
The measure of angle RTV can be determined using the properties of angles in a triangle.
In a triangle, the sum of all three angles is always 180 degrees. So if we know the measures of the other two angles, we can find the measure of RTV.
Let's say the measures of angles R and T are given as 50 degrees and 75 degrees, respectively.
To find the measure of RTV, we subtract the sum of the known angles from 180 degrees:
RTV = 180 - (R + T) = 180 - (50 + 75) = 180 - 125 = 55 degrees.
