1. suppose x and y are real numbers that satisfy [x] + {y} = 3.2 and {x} + [y] = 1.7, where [x] repreents th egreatest integer less than or equal to x and {x} = x - [x]. find the difference x - y 2. triangle ABC has mod(AB) = 5 and mod(BC) = 6 and mod(AC) = 7. A circle is inscriobed in the triangle,interesecting AB at D. Find mod(AD). This is something I cannot comprehend. If a circle is inscribed in a triangle, it only touches the sides but will not intersectthe side.
for the first problem this is how I started [x] + y - [y] = 3.2 x - [x] + [y] = 1.7 adding these x = y = 4.9 and subtring one from the other x[x] = y - 2[y] - x = 1.5 now I don't see a way ahead
