All angles add to 180 (interior angles)
22+53+?=180
75+?=180
minus 75 both sides
?=105
third angle is 105 degrees
Here is my answer, hope to help you
Answer:
Timed test.
Step-by-step explanation:
An operational definition gives exactly what the independent variable means and its mode of measurement. The Independent variable is the variable in a research or experimental study which causes a change in the the measured variable. Hence, the independent variable is the predictor variable. In the study above, the independent variable is the timed test which is used to observe changes in the heart rate of the test taker (test anxiety).

Answer:
3) x=60
6)x=86
9) x=40
Step-by-step explanation:
3) 60+60+x=180
120+x=180
X=180-120
x=60
6) 18+(x-8)+(x-2)=180
18-8-2+x+x=180
8+2x=180
2x=180-8
2x=172
x=172/2
x= 86
9) (2x+5)+60+(x-5)=180
2x+x+5+60-5=180
3x+60=180
3x=180-60
3x=120
x=120/3
x=40
