Question

if two adjacent angles of a quadrilateral are each equal to 75 degree, find the fourth angle​

Answer 1

Answer:

105 DEGREE

Step-by-step explanation:

LET , Sum of angles of a quadrilateral= 360 degrees

Given angles 75° and 75°

Let one of the other angle = x

so, the fourth angle is also x

so, 75°+75°+x+x= 360°

so, 150°+ 2x= 360°

so, 2x= 210°

so, x= 105°
