Question

if two angles of quadrilateral are in ratio 5:7 . find all angles of quadrilateral. answer it and show it​

Answer 1

Answer:

the angles of the quadrilateral are 150° and 210°

Step-by-step explanation:

let the ratio be x

so 5:7 becomes 5x and 7x

the sum of all angles of a quadrilateral= 360°

5x+7x=360°

let x be common

so,

(5+7)x= 360°

12x=360°

x=360÷12

x= 30

Now, the angle are

5x = 5×30= 150°

7x= 7×30 =210°

So, now the angles of the quadrilateral are 150° and 210°
