Vertical angles are always congruent, meaning they have the same measure. Therefore, the measure of the first angle is equal to the measure of the second angle:
115 = 164 - 7x
Now, solve for x:
7x = 164 - 115
7x = 49
x = 7
Therefore, the value of x is 7.
on a pair of vertical angles one angles measures 115 degrees and the other measures (164 - 7x) what is the value of x
