Question

The angles of a quadrilateral are 90°, 80°, 125° and xº. Find the value of x.​

Answer 1

Step-by-step explanation:

90+80+125+x=360

295+x=360

x=360-295

x=65

Answer 2

The total sum of all the angles of a quadrilateral is 360 degree.

Sum of given angles = 90° + 80° + 125°

= 295°

Measurer of angle x = 360-295

= 65°
