Answer 1

Step-by-step explanation:

Here, ACOD is a quadrilateral.

∠ADO=90

o

,∠DOC=75

o

,∠OCA=90

o

We know that, in quadrilateral sum of four angles is 360

o

.

⇒ ∠ADO+∠DOC+∠OCA+∠CAD=360

o

.

⇒ 90

o

+75

o

+90

o

+∠CAD=360

o

.

⇒ 255

o

+∠CAD=360

o

.

⇒ ∠CAD=360

o

−255

o

.

∴ ∠CAD=105
