Question

the angle of a quadrilaterall are in ratio 4:5:10:11 the angle are​

Answer 1

Step-by-step explanation:

Sum of the angles of quadrilateral = 360 degrees

4 : 5 : 10 : 11 = 4x + 5x + 10x + 11x

Therefore,

4x + 5x + 10x + 11x = 360 degrees

30x = 360 degrees

x = 12 degrees

First angle = 4x = 48 degrees

Second angle = 5x = 60 degrees

Third angle = 10x = 120 degrees

Forth angle = 11x = 132 degrees

May the answer helps you :)

Answer 2

Answer:

let the angles are 4x , 5x , 10x , 11x

4x+5x+10x+11x=360

=> 30x=360

=> x=360/30=12

so the angles are 4×12°=48° , 5×12°=60° , 10×12=120° , 11×12=132 °
