# In concave kite A B C D , there is an interior angle at vertex B that is a reflex angle. Given that m ∠ A = m ∠ C = m ∠ D = 30 ° , find the measure of the indicated reflex angle. To determine

To find:

The measure of the indicated reflex angle.

Explanation

Calculation:

Given,

A concave kite ABCD

mA=mC=mD=30°

In a kite the sum of all the interior angles is 360°.

Thus,

A+B+C+D=360°
