Where's the graph? it cant be solved without it
Hello,
a-3b=4 (1)
a-b=-2 (2)
(1)-(2)==> -2b=6
=>b=-3 and a=-2+(-3)=-5
Answer D
Proof
-5+3=-2
-5-3(-3)=4
Answer:
the angle of reflection is the angle between the reflected wave and the "normal" (the perpendicular line to the reflecting surface).
Step-by-step explanation:

Answer:
42 Degrees
Step-by-step explanation:
Angle ABF is parallel to the angle DCF
