Distinct angles are when the angles of a polygon are all different.
So here first you have to have same denominators to subtract and add.
to make same denominator you have to multiply something to them which meets up to their lowest common multiple (LCM). so here the easiest thing is multiply each denominator to the other but remember you have to multiply them to the numerator too.
3×9/5×9-2×5/9×5
so it becomes
27/45-10/45
17/45
as you cant bring to its simplest form since the answer in a prime no. leave it like that.
The answer is C. 1,000,000
D. 35, since that would be the longest amount. of time walking away from her house, she should be the farthest amount of feet away from her house
