Question

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

Answer 1

Answer:

135°

Explanation:

sum of angles in a quadrilateral = 360°

it's given that three of them are 75° each

let the fourth angle be x.

therefore 75° + 75° + 75° + x = 360°

=> 225° + x = 360°

=> x = 360° - 225°

=> x = 135°

hence, the fourth angle of the quadrilateral measures 135°

Answer 2

Explanation:

let fourth angle be x.

ATQ,

75+75+75+x=360

(angle sum property of a quadrilateral)

225+x=360

x=360-225

x=35
