Verified answer

10) 2n + 90° + 3n = 180°
                        5n = 180° - 90°
                        5n = 90°
                          n = 18°
       <FMG = <JMK
                  = 3 n
                  = 3 x 18°
                  = 54°
11) karena KLM siku-siku maka
      6a + 3a = 90°
              9a = 90°
                a = 10°
      <NLM = 3 a
                 = 3 x 10°
                 = 30°
12) <DOE = 180° - <COD
                 = 180° - 147°
                 = 33°
      <AOB + <AOE + <DOE = 180°
             <AOB + 90° +33°   = 180°
                               <AOB   = 180° - 90° - 33°
                                            = 57°
