Answer 1

Answer:

$86^{o}$, $129^{o}$

Step-by-step explanation:

ratio of other two angles = 2:3

sum of two angles of quadrilateral = $145^{o}$

sum of angles in a quadrilateral = $360^{o}$

let the two angles be 2x, 3x

     2x + 3x + $145^{o}$ = $360^{o}$

            5x + $145^{o}$ = $360^{o}$

                     5x = $360^{o}$ - $145^{o}$

                     5x = $215^{o}$

                      x = $215^{o}$/5

                      x = $43^{o}$

therefore

               one angle : 2x = 2($43^{o}$) = $86^{o}$

             other angle : 3x = 3($43^{o}$) = $129^{o}$
