Answer: a) 0.068 rad b) 0.1334 rad
Explanation: Angular size is an apparent size of an object seen by an individual. To calculate it, in radians, the formula is:
θ = [tex]\frac{S_{ap}}{l}[/tex], where:
[tex]S_{ap}[/tex] is the apparent size measured;
l is the distance between the object and the observer;
a) For you, the dime's angular size is
θ = [tex]\frac{1.7}{25}[/tex] = 0.068rad
b) For your uncle:
θ = [tex]\frac{1.7}{15}[/tex] = 0.1134rad
So, for your uncle, due to his myopia, the dime seems bigger than for you, who has normal vision.
