Answer:
Pls mark brainlist.
Step-by-step explanation:
From the figure:-
∠DAO=∠BCO (Alternate interior Angle)
=30
o
(Two parallel lines are crossed by a transversal)
We know that Diagonals in a rhombus intersect at right angle so ∠BOC=90 …………..(1)
through vertically opposite Angles AOD=90
o
Now takes ΔBOC
∠BOC+∠OCB+∠CBO=180
o
90
o
+30
o
+∠CBO=180
o
∠CBO=180−120
o
∠CBO=60
o
……………(2) Ans
∠OCB=∠OAD (Alternate interior Angle)
=30
o
…………..(3) Ans
All the four triangle should be similar by this in ΔAOB.
∠AOB=90
o
∠OAB=30
o
∠ABO=60
o
.
1. a=15 (the diagonal of the rhombus bisect each other
perpendicularly)
2.b=15 ( same as 1)
3. c= 17 (the sides of the rhombus are equal)
Which is the required information.
