The ray Q-S divides a straight angle P-Q-R into angle P-Q-S measuring x degrees and angle R-Q-S measuring x minus 60 degrees.
Which equation can be solved to find the measure in degrees of ?
A.2x-60=180
B.2x-60=90
C.x-60=90
D.x-60=180
The correct equation that can be solved to find the measure in degrees of angle P-Q-S is:
B. 2x - 60 = 90
This equation represents the fact that the sum of angle P-Q-S and angle R-Q-S is equal to 180 degrees (the measure of a straight angle). Solving for x will give the measure of angle P-Q-S.
