The angle sum property of a triangle:

  • The total measure of the three angles of a triangle is 180°


\large\bf{\red{ \longrightarrow}} \: \tt \: x \: + \: 44 \degree \: + \: 29 \degree \: = \: 180 \degree


\large\bf{\red{ \longrightarrow}} \: \tt \: x \: + \: 73 \degree \: = \: 180 \degree


\large\bf{\red{ \longrightarrow}} \: \tt \: x \: = \: 180 \degree \: - \: 73 \degree \:


\large\bf{\red{ \longrightarrow}} \: \tt \: x \: = \: 107 \degree

⇛ Value of x is 107°

Using angle sum property


\\ \sf\longmapsto x+44+29=180


\\ \sf\longmapsto x+63=180


\\ \sf\longmapsto x=180-63


\\ \sf\longmapsto x=117°
