Question

In a quadrilateral ABCD, the angles A, B, C and D are in the ratio 1 : 2 : 4 : 5. Find the measure of each angles of the quadrilateral.

Answer 1

Answer:

HEYAA ,,

Step-by-step explanation:

LET THE RATIO BE :

1X : 2X : 4X : 5X

KNOW THAT (SUM OF ALL ANGLES OF A QUADRILATERAL IS 360°)

A/Q

1X : 2X : 4X : 5X =360

1X + 2X +4X +5X =360

12x = 360

x= 360/12

X = 30°

SO,

1X = 1 ×30 =30

2X = 2×30=60

4X = 4×30=120

5X =5×30=150

Answer 2

Answer:

30,60,120,150

Step-by-step explanation:

let the angles be x,2x,4x,5x

Sum of all angles=360°

ATQ,x+2x+4x+5x=360

=12x=360

=x=30
