Answer 2

Answer:

LODC=50°,LODC=40°

LAOB=90°,LCOD=90°

Step-by-step explanation:

(Ls is angle sign )

given that ,

LOAB=50°

LOBA=40°

Therefore ,LOAB=LODC=50°

[since it is alternating Ls]

again,

LOBA=LOCD=40°

[Since it is alternating angles]

here we know,

{sum of all angles of triangle is 180°}

so, LAOB+LOAB+LOBA=180°

so LAOB=180°-(50°+40°)

= 90°

therefore LAOB=LCOD=90°[since vertically opposite angles]

therefore

LODC=50°,LODC=40°

LAOB=90°,LCOD=90°

four angles☺
