Final answer:
Without knowing the value of angle 'w', it's not possible to determine the measure of 'r'. The equation for the question is 'r = 2w', meaning 'r' is twice the measure of 'w'. The specific measure of 'r' can only be determined if 'w' is known.
Step-by-step explanation:
The subject of the question is Mathematics and it's about geometry concepts in particular. Unfortunately, without knowing the value of 'w' it's impossible to determine the actual measure of 'r'. As for the equation that involves the angle 'r', the measure of 'r' is equivalent to twice the measure of 'w'. The equation is as follows: r = 2w. The possible measures of 'r' can only be known when we have the actual value of 'w'. So, in a nutshell, the question you've asked cannot be solved without the exact measure of 'w' given.
