It at the top all you had to do was divided bot ways you will get that answers
Answer:
B) Rotation, then Reflection
Because of the Vertical Angles theorem, we know that the two expressions are equal.
6x - 35 = 4x + 11
Add 35 to both sides: 6x = 4x + 46
Subtract 4x from both sides: 2x = 46
Divide by 2 on both sides: x = 23
Now, insert x into one of the equations: 6(23) - 35
138 + 35
103
103 + K = 180
Subtract 103 from both sides: K = 77
K = 77
Answer:
Use law of sine
sin90/9=sinB/4
4sin90/9=sinB
sin^-1(4sin90/9)=(sinB)sin^-1
=26.3877999612
26.39 degrees
