Question

2. The three angles of a quadrilateral are 80°. 70° and 120°. The fourth angle is
(a) 110°
(b) 100°
(c) 90°
(d) 80
3. The angles of a quadrilateral are in the ratio 3:4:5:6. The largest of these angles is​

Answer 1

Answer:

Step-by-step explanation:

2)90

3)

let the angle be taken as x

3x+4x+5x+6x = 360

18x=360

x=20

the angles are 60,80,100,120

largest angle is 120

Answer 2

Answer:

1) The three angles of a quadrilateral are 80°. 70° and 120°. The fourth angle is :

Sum of angles of a quadrilateral is

equal to 360° .

The fourth angle is : 90° .

2) Sum = 3x + 4x + 5x + 6x = 360°

18x = 360°

x = 20°

The largest angle is 6(20) = 120°
