Answer:
Step-by-step explanation:
7) The tangent angles are 90° each.
The angles of a quadrilateral add up to 360°, so ? = 360°-90°-90°-73° = 107°.
8) Solve this the same way as question 7). ? = 360°-90°-90°-57° = 123°.
Questions 9) and 10) are cut off, so I assume you don't need to know those.
3) HK = 2√5
midpoint of HK = (8,8)
4) SR = 2√2
R = (6,2)
5) Instead of walking a total of 14 he only would have walked a total of 10.
Hope this helps! ;)
