m∠2= 52° (alt. ∠s)

m∠1 +m∠2= 180° (adj. ∠s on a str. line)

m∠1 +52°= 180°

m∠1= 180° -52°

m∠1= 128°

m∠3= 47° (alt. ∠s)

m∠4 +47°= 180°

m∠4= 180° -47°

m∠4= 133°

m∠5 +52° +47°= 180° (adj. ∠s on a str. line)

m∠5 +99°= 180°

m∠5= 180° -99°

m∠5= 81°

☆ The sum of the angles of a straight line is 180°.
