So let's say that the second angle is x.
Then we can say that the third angle is
.
So then we have three angles:
1) 66°
2) x°
3) (
)°
So then we can add these together and solve for x by setting it equal to the total degrees left in the triangle after subtracting the known angle:





So now we know that the measure of the second angle is 38°. So then we can use this value to solve for the third angle:

So the values of the angles are:
1) 66°
2) 38°
3) 76°

Answer:
B
Step-by-step explanation:
it between B and c not really sure though
Answer:
8,640
Step-by-step explanation:
One foot is 12 inches, so a square foot would be 144 inches (12×12 -> l×w) So, you would multiply 60 by 144, and you would get 8,640 square inches.
The length of line didn't change
the angle also not altered
the line of reflection is centered
