Abcd is a kite y=
I know x=90

  y = 50

Explanation:

For any kite, the adjacent sides are congruent.

This leads to AB = BC and AD = DC

Using the SSS congruence rule, we can prove triangle ABD is congruent to triangle CBD.

From that we can say

Angle ABD = Angle CBD

as these angles correspond to one another.

So this means angle ABD is y

Let E be the intersection point of the diagonals. Angle AEB is x = 90 as you found earlier. The diagonals of any kite are always perpendicular.

Focus on triangle AEB

The three angles of any triangle add to 180

A+E+B = 180

40+x+y = 180

40+90+y = 180

130+y = 180

y = 180-130

y = 50

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
