Question

Three angles of a quadrilateral are equal and the fourth angle measures 75 degree. What is the measure of each equal angles .
(With steps)

​

Answer 1

Step-by-step explanation:

We know that, sum of interior angles of quadrilateral is equal to 360°.

From the question it is given that, three angles of a quadrilateral are each equal to 75°.

Let us assume the fourth angle be x.

Then, 75° + 75° + 75° + x = 360°

225 + x = 360°

x = 360° – 225

x = 135°
