Answer:
how do u want meto read it?
Step-by-step explanation:
Answer is 4.
Right angle= 90
50+ 10(4)= 90
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°
