Explicație pas cu pas:

8a)

<AOD = 90° = <AOB + <BOC + < COD = 30° + x + 25° = 55° + x

x = 90° - 55° = 35°

8c)

<MTS = 180° = <MTP + <PTR + <RTS = x + 20° + 2x + x = 4x + 20°

4x = 180° - 20° = 160°

x = 160° : 4 = 40°

52°12'34'' x 3 = 156°36'102'' = 156°37'42''

31°25'24'' x 5 = 155°125'120'' = 155°127' = 157°7'

103°23'40'' : 5 = 100°203'40'' : 5 = 100°200'220'' : 5 = 20°40'44''

25°13'28'' + 57°34'15'' = 82°47'43''

63°29'18'' + 54°23'56'' = 117°52'74'' = 117°53'14''

114°32'45'' + 38°43'51'' = 152°75'96'' = 152°76'36'' = 153°16'36''

145°36'42'' - 92°21'34'' = 53°15'8''

104°13'19'' - 73°25'26'' = 103°73'19'' - 73°25'26'' = 103°72'79'' - 73°25'26''

= 30°47'53''
