if two angles equal 9x + 194 and 7x + 182 , how can you determine the measure of each angle?
A add the expressions
B subtract the expressions
C multiply the expressions
D ser the expressions equal to each other
D set the expressions equal to each other
9x + 194 = 7x + 182
9x - 7x = 182 - 194
2x = -12
x = -6
Now substitute x back into the original expressions to find the measures of each angle:
Angle 1: 9(-6) + 194 = -54 + 194 = 140
Angle 2: 7(-6) + 182 = -42 + 182 = 140
Therefore, both angles measure 140 degrees.
