Question

If three angles of a quadrilateral are each equal to 75° then find the fourth angle.

Answer 1

Answer:

the fourth angle will be

135

as the sum of 4 angles should be 360

so 75+75+75+x=360

x=360-225

x=135

Step-by-step explanation:

Answer 2

If all the three angle are of 75° then by the angle sum property u can find

It 75+75+75+x=360°.... 225+x=360...x=360-225 then the fourth angle will be of 135°
