Two angles are called supplementary angles if the sum of two angles is 180 degrees and they form a linear pair.
Here we are given than angle P and angle Q are supplementary angles.
Sum of angle P and angle Q will be 180.
Angle P measures 5x and angle Q measures 3x – 12
Adding the two angles,




x=24
Angle P = 5x
Angle P =5*24 =120
Answer: Angle P is 120 degrees.
The associative property is 6 times 3
Answer:
2
Step-by-step explanation:
5x is one term
+11 is another term
3x - 1 = 5x - 11
Add 1 to both sides.
3x = 5x - 10
Subtract 5x from both sides.
-2x = -10
Divide by -2.
x = 5
