When the lines are parallel and angles are given, and since a straight line is 180°, the 2 angles of the line intersecting the parallel lines have to add up to be 180. Therefore,
21. 31°
22. 96°
23. 149°
24. 84°
25. 53°
Answer:
/2
Step-by-step explanation:
/
=1.2422
/2=0.66 <-- not matching with the top expression.
/2=1.11<--not matching with the top expression.
/2=1.2422<-- matches!!
/3=0.91<-- not matching with the top expression.
The period is equal to 2pi/n, where n is the coefficient of t. In this case pi/2. Therefore the period in this example is 4. Frequency is equal to 1/period. Hence the frequency for this problem is 1/4
