1. Problem Description
The problem asks to find the measure of angle D in a kite ABCD, where angle A is and angle C is .
2. Solution Steps
A kite is a quadrilateral. The sum of the interior angles of any quadrilateral is . In a kite, one diagonal is the perpendicular bisector of the other. Also, a kite has two pairs of adjacent sides that are congruent. Moreover, the angles between non-congruent sides are congruent. In kite ABCD, since AB = BC, and AD = CD, we have .
We know that the sum of the interior angles of a quadrilateral is . Thus,
.
Given that and , and also , we can substitute these values into the equation:
.
Since , let .
