Question

Three angles of a quadrilateral are equal and the fourth angle is equal to
164. Find each of the equal angles of the quadrilateral​

Answer 1

Answer:

85°.

Step-by-step explanation:

Let the three angles be x

We already know that sum of all angles of quadrilateral is 360.

x + x + x + 105° = 360

3x + 105° = 360°

3x = 360° - 105°°

3x = 255°

x =  

x = 85°

Hence, the measure of three angles is 85°.
