Answer:
21. 65 degrees 20. 64 degrees 22. 25 degrees 23. 123 degrees
Step-by-step explanation:
m<ZWX= 50 degrees so that angle cut in half each side is 25 degrees. All 4 inner angles are 90 degrees cause they are right angles and every triangle has to add up to 180 degrees so 25+90=115 and 180-115=65 angle VZW= 65 degrees.
Covering what we went over earlier m<ZWX= 50 degrees and 50/2 equals 25 so ZWV= 25 degrees.
The two small right triangles are identical so if m<VXY=58 degrees then angle VZY=58 degrees also and all the middle angles are 90 degrees then ZYV=32 degrees and m<XYV+ZYV since they are the same angle measurement XYZ= 64 degrees
Finally angle VZY=58 degrees and VZW= 65 degrees so add them together and you get m<WZY= 123 degrees
