A triangular shaped lake-front lot has a perimeter of 1800 feet. One side is 100 feet longer than the shortest side, while the third side is 200 feet longer than the shortest side. Find the length of all three sides.

Which is a true statement about an exterior angle of a triangle a. it is formed by two segments that are not sides of the triangle, b. it forms a linear pair with one of the interior angles of the triangle, c. it is complementary to one of the interior angles of the triangle. d. it is formed by two segments that are sides of the triangle.

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'
