Question

the angles of quadrilateral are in the ratio 3:5:9:13 find all the angle of the quardrilateral

Answer 1

Hey !!

let the angles be 3x , 5x , 9x , 13x

Then

3x + 5x + 9x + 13x = 360
30x = 360
x = 360 / 30 = 12

Hence the angles are
3x = 3 × 12 = 36
5x = 60
9x = 108
13x = 156

Answer 2

total sum of the angle in the quadrilateral is 360
given ratio is 3:5:9:13

let that be as x so these become as 3x,5x,9x,13x.
so add all now then
3x+5x+9x+13x=360
30x = 360
x = 12
now substitute in all the values ie 3x,5x,9x,13x
then
3x= 3 into 12 = 36
5x= 5 into 12 =60
9x=9 into 12 =108
13x=13 into 12 =156
these are the angles if u add aslo ull get 360 
hope ull get the answer and mark as brainliest one
