Question

the angle of a quadrilateral are in the ratio of 2ratio 4 ratio 5 ratio 7 find angle

Answer 1

Let the angles are :-
2x, 4x, 5x, 7x


2x+4x+5x+7x =360

6x+12x =360

18x =360°

x =360/18

x =20

Angles are:-

2×20=40°
4×20=80°
5×20=100°
7×20=140°


I hope this will help you

Answer 2

Hello friends!!

Let the angles be

2a , 4a , 5a and 7a .

As we know that,

Sum of all the internal angles of a Quadrilateral is 360°.

According to question,

2a + 4a + 5a + 7a = 360

18a = 360

$a = \frac{360}{18}$

$a = 20$


Now, all the angles are :

2a = 2 × 20 = 40°

4a = 4 × 20 = 80°

5a = 5 × 20 = 100°

7a = 7 × 20 = 140°



HOPE IT HELPS YOU..
