Answer 2

Answer:

<STM = 50°

<SON = 50°

<NSM = 50°

Step-by-step explanation:

< STM = 180°- (40°+ 90°) (angle sum property of )

=> 50°

<O = <T ( Opposite angle of //gram)

=> <O= 50°

<S = <OSN+<NSM+<TSM

<S = <L (Opposite angles of//gram)

<L = 180°- <T

=180°- 50°

=>. <L = 130°

=>. <S = 130°

=> <NSM = 130°- (50°+ 40°)

<NSM = 50°
