Question

Find the value of x in the triangle shown below.(not a test just need help with khan academy)

Answer 1

Using angle sum property

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

$\\ \sf\longmapsto x+63=180$

$\\ \sf\longmapsto x=180-63$

$\\ \sf\longmapsto x=117°$

Answer 2

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°
