Question

The angles of quadrilateral are in the ratio. 4 : 5 : 10 : 11 . then angles are
1 point
a. 36°, 60°, 108° , 156°
b 48°, 60°, 120°, 132°
c. 52°, 60°, 122° , 126
d. 60°, 60°, 120°, 120°​

Answer 1

Answer:

b is the correct answer

Step-by-step explanation:

let the first angle be 4x

second be 5x

third be 10x

and forth be 11x

ACCORDING TO QUESTION

4x +5x +10x +11x =360°

30x =360°

x = 360°/ 30

x = 12

first angle 4×12= 48

second angles = 5×12=60

third angle = 10×12=120

forth angle = 11×12 =132

Answer 2

Answer:

b

Step-by-step explanation:

sum of all angles of a quadrilateral is 360

so from question let the angles are 4x,5x,10x,11x

so

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

30x=360

x=12

so angle are 4x= 4*12=48

5x= 5*12=60

10x= 10*12=120

11x=11*12=132
