Question

the three angles of a quadrilateral are 60degrees, 60grades,and 150 degrees then fourth angle is

Answer 1

thus the fourth angle of quadrilateral is 90
answer is 90 degree

Answer 2

Hello friend....☺

Here is your solution....☺

♦ Let the fourth angle of the quadrilateral be "x"

=> 60° + 60° + 150° + x = 360° [ sum of all angles of a quadrilateral is equal to 360°]
=> 270° + x = 360°
=> x = 360° - 270°
=> x = 90°

Hence, the fourth angle of the quadrilateral is a right angle i.e; 90°.
