Question

The angles of a quadrilateral are in the ratio 1:2:4:5. Find all the angles of the quadrilateral.

pls answer only if you know the answer to my question.​

Answer 1

Hi mate..........

Let the angles of the quadrilateral be x, 2x, 4x, 5x.

According to angle sum property of quadrilateral sum of all angles should be 360°.

Thus,

$x + 2x + 4x + 5x = 360$

$12x = 360$

$x = 30$

So, all angles are 30°, 60°,

120°, 150°.....................

Hope this helps you.

Answer 2

Answer:

Step-by-step explanation:

Let all angles =X

One angle =1×x=X

Angle two = 2×x =2x

Angle three = 4x

Angle fourth = 5x

The sum of all side of quadrilateral is = 360

X+2x+4x+5x=360

12x =360

X=360/12

X=30

Now angle one equal to 30

Second angle= 60

Third angle =120

Fourth angle = 150
