Question

Three angles of a quadrilateral are equal and the fourth angle is 1500. What is the measure of each of the equal angles?

Answer 1

70°

correction: fourth angle = 150°

Step-by-step explanation:

let measure of three equal angles of quadrilateral be 'x'

x + x + x + 150° = 360°

3x = 210 => x = 70°

measure of each of the equal angles is 70°
