Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

What are two numbers that have a sum of 15
