Sum of two interiors=exterior
[tex]\\ \sf\longmapsto x+72=90+34[/tex]
[tex]\\ \sf\longmapsto x+72=124[/tex]
[tex]\\ \sf\longmapsto x=124-72[/tex]
[tex]\\ \sf\longmapsto x=52[/tex]
Step-by-step explanation:
According to question,
x+72°=90°+34° because the sum of two interior angles is equal to the opposite exterior angle.
x+72°=124°
x=124°-72°
x=52°
