19.5
Step-by-step explanation:
u just divide 39 by 2 and get 19.5
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
Answer:16
Step-by-step explanation:
2/4 = 1/2
8+8=16
The lengths of the bases would be 3 and 9
Step by Step Description:
