Answer 1

Two straight lines intersect each other in such a way that one of the formed angles is 90°. To find, Remaining angles are also 90°. According,to the data mentioned in the question one of the formed angles is 90°.

please thank my answers

Answer 2

Step-by-step explanation:

Other three angles are = ∠AOC,∠AOD and ∠BOD. Now,AB is a straight line. So,the ∠AOB will be 180°. We know that,the vertical angles which are created by the intersection of two straight lines,are equal
