Three angles of a quadrilateral are equal. Fourth angle is of measure

1.	Three angles of a quadrilateral are equal. Fourth angle is of measure 150°. What is the measure of equal angles?
Answer» We know that Sum of angles of a quadrilateral is = 360° Let each angle be x° So, 150° + x° + x° + x° = 360° 3x° = 360° – 150° x°= 210°/3 = 70° ∴ Value of equal angles is 70° each.

Answer»

We know that Sum of angles of a quadrilateral is = 360°

Let each angle be x°

So,

150° + x° + x° + x° = 360°

3x° = 360° – 150°

x°= 210°/3

= 70°

∴ Value of equal angles is 70° each.
