Indefinitely many
The lines are on each other so every solution is correct
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
Answer:16
Step-by-step explanation: 8(25−3)÷11
8(22)
176 divided by 11= 16
Answer: possible result of an experiment
Step-by-step explanation: in probability theory, An outcome is a possible result of an experiment. Each possible outcomes of a particular experiment is unique, and different outcomes are mutually exclusive (Only one outcome Will occur on each trial of the experiment). All of the possible outcomes of an experiment formed elements of a sample space.
