#7 is kind of hard to read
Answer:
19. parallel
20. corresponding
21. exterior
22. corresponding exterior angles
if not for the points i wouldve left u to suffer on ur own so yor welcome
If is an acute triangle, all the angles should be acute angles.
180-38=142°
142-69=73°
So your answer is 69°, lovely~
Answer:
The line AB, with A(Ax, Ay), B(Bx, By) and midpoint M(Mx, My) satisfying:
Ax + Bx = 2Mx
Ay + By = 2My
=>
2 + Bx = 2*1
5 + By = 2*2
=> Bx = 0
=> By = -1
=> B(0, -1)
Hope this helps!

Answer:
The coordinates are and .
Step-by-step explanation:
First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:
(1)
Where is the vector translation.
If we know that and , then the vector translation is:
Then, we determine the coordinates for Y' and Z':
The coordinates are and .
