Answer:
Part 1)
Part 2)
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
Part 1) Find the measure of angle 1
we know that
The longer diagonal of a kite bisects the kite into two equal parts
That means
In this problem the longer diagonal is the segment AC
Part 2) Find the measure of angle 3
we know that
The intersection of the diagonals of a kite form 90 degrees.
That means ----> The triangle ADO (O is the intersection point both diagonals) is a right triangle
so
----> by complementary angles in a right triangle
