Given :

  • Ratio of two supplementary angles is 4 : 1

To Find :

  • The measures of both angles

Solution :

• Let the ratio constant be 'x'

Then the both angles are 4x , 1x

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

• Using the relation ,

 \\   \star \large\boxed{\sf{ \purple{sum \: of \: two \: supplementary \: angles = 180 {}^{ \circ} }}} \\

 \\   : \implies \sf \: 4x + 1x = 180 {}^{ \circ}  \\  \\  \\   : \implies \sf \: 5x =  {180}^{ \circ}  \\  \\  \\   : \implies \sf \: x =  \frac{ {180}^{ \circ} }{5}  \\  \\  \\   : \implies{\boxed{\sf{\underline{x = 36 {}^{ \circ} }}}}

Then the both angles are ,

 \\  \sf \: 4x = 4(36) = 144 {}^{\circ}  \\  \\  \sf \: 1x = 1(36) =  {36}^{ \circ}  \\

Hence , The Measures of both angles are 144° and 36° .

Answer:

Let the ratio of two supplementary angles be 4x and x .

4x + x = 180°

5x = 180°

x = 180°/5

x = 36°

therefore 4x = 4×36°

= 144°

Therefore 36° and 144° are the two supplementary angles.
