38 - 171 divided by 19 times 2
If Dylan owes half as much as he used to that would imply that the 28$ would be divided by two which would be 14$, which means that half of what he owed 28$ would now be 14$.
Sum of angles in a triangle is 180°
90 + (x + 15) + (2x) = 180
90 + x + 15 + 2x = 180
105 + 3x = 180
3x = 180 - 105
3x = 75
x = 75 ÷ 3
x = 25
Smaller angle = x + 15 = 25 + 15 = 40°
Larger angle = 2x = 2(25) = 50°
Answer: 50°
