Question

The angles of a quadrilateral are in the ratio 4:7:15:10.Which is the largest angle of this quadrilateral 



120°

180°

150°

100°

Pls help! ​

Answer 1

Answer:

Let the sides be = 4x,7x,15x,10x

Sum of all the angles in a quadilteral =360°

4x+7x+15x+10x=360°

= 36x=360°

=x=360÷36

=x=10°

‎ ‎

‎ ‎

So, angles are -

4x=4×10=40°

7x=7×10=70°

15x=15×10= 150°

10x=10×10= 100°

$\rightarrow$Largest angles of quadrilateral =150°

Answer 2

Answer:

150°

Step-by-step explanation:

4x+7x+15x+10x=360

36x=360

x=10

here the biggest angle is 15x

so the angle will be=15×10=150°
