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°
Answer:
C and D
Step-by-step explanation:
A P E X verified
X-intercept can be found when y=0
y-intercept can be found when x=0
Plug in x=0 to find the y-intercept
-3(0) + 4y = -12
4y = -12
y = -3
Plug in y=0 to find the x-intercept
-3x + 4(0) = -12
-3x = -12
x = 4
The x-intercept is (4,0)
The y-intercept is (0, -3)
