Answer:
θr = 55.2 °
Explanation:
The law of reflection states that the angle of incidence and the angles of reflection is the same.
Let's use trigonometry to find the angle between the reflected ray, where the horizontal distance x = 55.9 cm and the vertical distance is y = 38.9 cm
tan θ = y / x
tan θ = 38.9 / 55.9
θ = tan⁻¹ (0.6959)
θ = 34.8°
This angle is measured with respect to the x-axis (horizontal), but in general the angles in optics are measured from the y-axis so that the angle is
θ = 90 - 34.8
θr = 55.2 °
Answer:
answer that in your parents
Answer:
Long short
Explanation:
1
Dogs that are bigger are selected to be parents.
2
The parents are bred together, and their offspring will be different sizes.
3
The biggest offspring will be selected and bred together.
4
This cycle continues until the dogs have been selectively bred to be bigger than the current world record size.
5
Selective breeders need to ensure that they are not also selecting for disadvantageous traits, like genetic limb defects.
