[tex]\text{We can solve this in simple terms:}\\\\\text{We know that the line going vertical is perpendicular to the line going}\\\text{horizontal}\\\\\text{This means that the section should equal to 90 degrees}\\\\\text{We know that 28 is one of the values, but we need another value that would}\\\text{make 90}\\\\\text{So subtract 28 from 90}\\\\90-28=62\\\\\boxed{\text{x = 62 degrees}}[/tex]
