Question

The four angles of a quadrilateral are in the
ratio of 3:4:5:6. The largest angle is:
(A) 160 (B) 80
(C) 100 (D) 120​

Answer 1

Answer:

option d) 120 is correct

Step-by-step explanation:

let common multiple be x

sum of all angles of quadrilateral is 360 degree

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

18x=360

x= 20

largest angle =6x =120.

Answer 2

make the below answer will be helpful to you:

we know that the sum of all angles of a quadrilateral is equals to 360 degree.

so you can solve it by the below simplification:

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

18x=360'

x=360'/18

x=20

so all angles =3x = 3 x 20 = 60

4x = 4x20 = 80

5x = 5x20 = 100

6x = 6x20 = 120.

show the angle which is 6x i.e.120 . so option d is the correct answer of this question.

I have written the complete solution of the question.

may this will be helpful to you.

have a bright future ahead.
