Question

two angles of quadrilateral is 90 degree and remaining two angles are such that one is three times the other find these two angles

Answer 1

Let the third angle be x and fourt angle be 3x


A.T.Q


1+2+3+4=360 (angle sum property of quad.)
90+90+x+3x=360
180+4x=360
4x=360-180
4x=180
x=180/4
x=45


Therefore third angle = 45
and fourth angle = 3×45= 135

Answer 2

Answer:

Let the third angle be x°

Let the fourth angle be 3x°

Sum of angles of a quadrilateral = 360°

= x° + 3x° + 90° + 90° = 360°

4x° + 180° = 360°

4x° = 360° - 180°

4x° = 180°

x° = 180/4

x° = 45°

Third angle = 45°

Fourth angle = 45 × 3

= 135°
