Step-by-step explanation:
Answer:
answer is D
Step-by-step explanation:
If AB and AC are the same that means that <B and <C are the same and since all sides must add up to 180 degrees then you add angles C and B together and subtract by 180.
180-80=100
Answer:
D’=(3,3); F’=(-2,-2); E’= (-5,0)
Step-by-step explanation:
To find the reflection over the y axis (the line x=0), you just need to change the x either from positive to negactive or the opposite.
Answer:
It's an angle bisector as it cuts the angle into 2 equal pieces
Answer:
Step-by-step explanation:
(x-2)(x+4)=x^2+4x-2x-8=0=> x =2, x=0
