Question

किसी चतुर्भुज के चारो कोण 1:3:7:9 के अनुपात मे है तो कोण ज्ञात करो ​

Answer 1

Answer:

Measure of the angles are :-

18° , 54° , 126° and 162°

Step-by-step explanation:

Let, the angles be, x, 3x, 7x and 9x

Since , we know that the sum of all the angles of a quadrilateral is 360° ,

Therefore,

x + 3x + 7x + 9x = 360°

=> 20x = 360°

=> x = 360°

Now , the required angles are :-

First angle =18°

Second angle = 18°×3 = 54°

Third angle = 18°×7 = 126°

Fourth angle = 18°×9 = 162°
