Answer:
1: 30 degrees
Step-by-step explanation:
In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.
Mathematically:
Angle of incidence = Angle of reflection
From the above question, the angle of incidence is on a smooth plane mirror = 30°
Since:
Angle of incidence = Angle of reflection
30° = 30°
Therefore, based on the law of reflection, the Angle of reflection = 30°
First one:
2.632 • 104 = 273.728
Second one:
2 • 10 - 7 = 13
Answer:
x=-1 y =-1
Step-by-step explanation:
multiply equation 1 with (-2)
+6x-2y=-14
5x+2y=3
now add equation 1 to equation 2
11x=-11
x=-1
now substitute x=1 in 1 or 2
5(1)+2y=3 5+2y=3 2y=3-5 2y= -2 y= -1
Answer:
y =
