Answer:
x= 2.7734 m
Step-by-step explanation:
Given the angle of incidence θ= 33.0°
distance from laser point and mirror = 1.10 m
laser point is 1.80 m above the floor
let the distance between mirror base and laser beam striking the floor after reflection = x
figure has been attached and from the from the figure we can write



putting value and solving we get
x= 2.7734 m
