[tex]\bold{\huge{\underline{ Solution\: 1 }}}[/tex]
Here,
- We have the measurement of two angles that is 40° and 60° .
- We have to find the value of x
We know that,
- The sum of angles of triangles are equal to 180° .This is known as Angle sum property.
By using Angle sum property
[tex]\sf{ 40{\degree} + 60{\degree} + x= 180{\degree}}[/tex]
[tex]\sf{ 100{\degree} + x = 180{\degree}}[/tex]
[tex]\sf{ x = 180{\degree} - 100{\degree}}[/tex]
[tex]\sf{ x = 80{\degree}}[/tex]
Hence, The value of x is 80° .
[tex]\bold{\huge{\underline{ Solution\: 2 }}}[/tex]
Here, We have
- The measurement of 2 angles that is 65° and 35° .
- We have to find the value of x
By using Angle sum property :-
[tex]\sf{ x + 65{\degree} + 35{\degree} + x= 180{\degree}}[/tex]
[tex]\sf{ x + 100{\degree} = 180{\degree}}[/tex]
[tex]\sf{ x = 180{\degree} - 100{\degree}}[/tex]
[tex]\sf{ x = 80{\degree}}[/tex]
Hence, The value of x is 80° .
