Question

the angles of a quadrilateral are in the ratio 1:2:4:5 find the angles

Answer 1

HEYA!!

SUM OF ANGLES OF QUAD = 360

LET ANGLE BE

X,2X,3X,4X

ADD THRM

10X= 360
X= 36

SO, 1 ANGLE = 36
2ND = 72

3RD = 108

4TH = 144

HOPE IT HELPS U MATE

Answer 2

WE KNOW THAT SUM OF ANGLE OF QUADRILATERAL =360°
IF YOU DONT KNOW THEN YOU CAN FIND OUT BY THE FORMULA OF THIS

IN WHICH n MEANS SIDE
(n-2)180
SO QUADRILATERAL HAS 4 SIDES
THEREFORE, WE PUT THE VALUE OF n AS 4

(4-2)180
2×280
360°

LET THE RATIO OF QUADRILATERAL BE '1x' , '2x' , '3x' , '4x'

A/Q. 1x +2x +3x +4x =360
10x =360
x = 360/10
x =36°

1x = 1×36 =36°
2x =2×36=72°
3x =3×36=108°
4x =4×36 =144°
HENCE, THE ANGLE ARE -: 36° , 72° , 108° , 144°
